What is AR 15 Buffer Tube? 🔍
⚫️ The AR-15 buffer tube, also known as the receiver extension, is a component of the AR-15 rifle platform. It is a cylindrical tube located at the rear of the rifle’s lower receiver, where the stock attaches.
Features 💎
- ☑️ Material: The buffer tube is typically made of high-quality materials such as aluminum or steel, providing durability and strength.
- ☑️ Length: They come in different lengths, including rifle length, carbine length, and pistol length. The length you choose depends on the specific AR-15 configuration you’re using.
- ☑️ Diameter: They are available in different diameters, with the mil-spec (military specification) being the most common. Mil-spec tubes have a diameter of 1.148 inches, while commercial buffer tubes are slightly larger at 1.168 inches.
- ☑️ Tube Type: These tubes can be categorized into two types: fixed and collapsible. Fixed buffer tubes are non-adjustable and provide a solid and rigid stock platform. Collapsible buffer tubes, often referred to as adjustable or telescoping, allow for length adjustment, providing versatility and accommodating different user preferences.
- ☑️ Mounting Options: The tubes have attachment points for the stock, either through a threaded end or a sling mount. These mounting options allow for the secure installation of the stock onto the buffer tube.
- ☑️ Buffer Weight: The buffer tube houses the buffer, which helps control the recoil of the firearm. Buffers come in various weights to accommodate different ammunition types and shooting preferences.
Benefits 🔐
- 💣 Recoil Control: The buffer tube, in conjunction with the buffer, helps reduce recoil and muzzle rise, making it easier to control the firearm during rapid or sustained fire. This results in improved accuracy and faster follow-up shots.
- 💣 Versatility: The collapsible options offer adjustable length settings, allowing users to customize the length of pull to fit their individual needs and shooting positions. This versatility makes the AR-15 adaptable to various shooting scenarios, including close-quarters combat and long-range engagements.
- 💣 Comfort and Ergonomics: With adjustable length options, shooters can achieve a more comfortable and ergonomic shooting position, enhancing the overall shooting experience and reducing fatigue during extended use.
- 💣 Stock Options: It serves as the attachment point for the stock, providing options for various stock designs and configurations. This allows shooters to choose stocks that align with their shooting style, body size, and personal preferences.
- 💣 Durability and Compatibility: Buffer tubes are constructed from sturdy materials, ensuring long-lasting durability and resistance to wear and tear. Additionally, they are designed to be compatible with a wide range of AR-15 components, including stocks, ensuring easy customization and upgrades.
- 💣 Sling Attachment: They often have built-in sling mounts or attachment points, allowing for the attachment of slings for improved weapon retention, carry options, and ease of transition between shooting positions.
How to Install a Buffer Tube Assembly? 🔧
👣 After deep research, our team revealed that installing a buffer tube assembly typically involves the following steps:
| 1️⃣ Ensure you have the necessary tools and components: You will need a buffer tube assembly, a castle nut, a receiver end plate, a carbine buffer, a buffer spring, and a stock or brace compatible with the buffer tube. | 6️⃣ Install the buffer: Insert the buffer into the buffer tube. The buffer typically weighs one end and a rounded end on the other. The rounded end should face towards the receiver while the weighted end should face away from it. |
| 2️⃣ Safety check: Before starting any work on a firearm, make sure it is unloaded and the chamber is empty. Double-check that there is no ammunition present in the area. | 7️⃣ Thread the buffer tube: Carefully thread it onto the lower receiver. Turn it clockwise until it is snug against the receiver. Be careful not to cross-thread it. |
| 3️⃣ Disassemble the lower receiver: If your firearm is already assembled, you’ll need to remove the stock or brace and any other components attached to the tube. This typically involves removing the retaining screw or pin that holds the stock or brace in place. | 8️⃣ Align the buffer tube: While holding it in place, align the castle nut with the notches on the receiver end plate. Thread the castle nut onto the buffer tube and tighten it using an armorer’s wrench or a castle nut wrench. Make sure it is securely tightened, but avoid overtightening. |
| 4️⃣ Install the receiver end plate: Attach the receiver end plate to the buffer tube. The end plate usually has a small loop on one side. Align the holes on the end plate with the holes on the tube and slide it into place, ensuring it sits flush against the end of the buffer tube. | 9️⃣ Final adjustments: Check the alignment of the tube and castle nut. If necessary, adjust the position of the buffer tube and retighten the castle nut until everything is properly aligned. |
| 5️⃣ Insert the buffer spring: Insert the buffer spring into the buffer tube. The large end of the buffer spring should go into the tube first. Ensure the spring is properly seated inside the tube. | 🔟 Attach the stock or brace: Once the buffer tube assembly is securely installed, attach your desired stock or brace to the buffer tube. Follow the manufacturer’s instructions for proper installation. |
🔔 Remember to consult the specific instructions provided by the manufacturer of your firearm and components, as the process may vary slightly depending on the model and design. ⚠️ If you are unsure about any step of the installation process, it is recommended to seek assistance from a qualified gunsmith or an experienced individual.

2# Bravo Company MFG AR 15 Buffer Tube
BCM has created one of the best solutions for the AR15 / M4 / M16. This is a complete receiver extension kit that works with a carabiner damper and action springs. It is compatible with the Sig Tac SB15 pistol stabilization bracket and is ATF compatible. The lower parts for AR15 are produced in 7075 T6 anodized aluminum. The coating complies with Mil-A-8625F, Type 3, Class 2. It is very tough and resistant to abrasion and corrosion. The finish is smooth and uniform to match the bottom of the AR15 perfectly. An important caveat, a pistol buffer tube will not work with a shock wedge gun retainer, as this requires a dedicated carbine buffer tube. Therefore, it will not work to put on the buffer tube from Bravo. The outer diameter of the buffer tube from BCM is 1.2 inches. Weight adjustment is not provided with this assembly. You will always get 2.9 ounces, but it will be a perfectly balanced system. As a nice addition, the Bravo pistol buffer has a QD mount suitable for one-point and two-point strings.
3# Aero Precision AR 15 Rifle Buffer Tube

5# Guntec USA AR-15 Mil-Spec Buffer Tube Set (6-Position)
This offer is used on many internet sites, but only the optical planet provides such a sweet price. If there is no difference in the products you buy, why pay more? 🙂 This Guntec USA AR-15 Mil-Spec 6 Position Buffer Tubing Set is made of T6 aluminum and comes in 5 different buffer tube colors.

6# Phase 5 Weapon Systems Inc AR-15 Buffer Tube
Phase 5 Weapon Systems Inc AR-15 Pistol Buffer Tube Complete Assembly PBT-CA is an offer not to be missed. This offering is packed with everything you need for a quick setup right out of the box. The hallmark of these bottoms for your AR15 is thicker foam padding and improved spring-loaded cushioning. The aluminum buffer tube is CNC machined and carefully checked by the quality control department. For production, only certified billets made of 7075 T651 aluminum are used, which is why the creation process is so well-oiled. After processing, the part is covered with Type III hard black anodizing. The entire design is fully compliant with high Mil-Spec requirements.
The design of the bottom remains attractive thanks to the military-inspired finish. This is not only beautiful but also better protects against corrosion and abrasion of components. Installation is also very simple and even enjoyable. The bottom groove is machined to remain compatible with all Mil-Spec end plates and lanyard accessories. This is to ensure Phase 5 PBT-CA compatibility with Sig Sauer without unnecessary side movements while firing the pistol.
Now some exact numbers. The bottom is 7.4 inches long with a total diameter of 1.25 inches. Together with this, it weighs only 4.8 ounces, while the spring resistance does not exceed 3 ounces. It works perfectly with PBT-CA pistols and others like the AR-15.
The kit includes an endplate with a lock nut, a foam pad, a karabiner buffer, and a reinforced phase 5 buffer spring. This is all you need for installation and has already been carefully added by phase 5. The only addition that would make this assembly a flawless kit is the QD lanyard. at the end of the tube. Otherwise, it is a great product with excellent functionality.
7# CMMG, Inc Receiver AR-15 Buffer Tube
CMMG is adept at making top-notch weapon add-ons, and this time it’s an add-on for the AR-15 rifles. The receiver extension kit is designed to work with standard NATO rifles and, of course, supports 5.56mm caliber. The extended receiver kit is Mil-Spec 6-position compliant and will suit almost any build of yours. This tube is made of high-quality anodized aluminum. Unfortunately, we did not find the exact marking of which aluminum it is, but it is really durable. The matte black finish protects the lower parts from corrosion and hides small scratches. It looks very decent and pleasant to the touch.
This kit includes: a 6-position CMMG carabiner buffer tube, CMMG carabiner spring, CMMG carabiner shock absorber, castellated nut, and endplate. This kit from CMMG is designed to work correctly with NATO standard rifles (5.56mm caliber) and standard AR rifles. This update is well-stocked and will definitely fit one of your arsenal’s rifles. CMMG makes good components but does not know how to fill out a product card on the site. Anyway, we tested it on our builds and can now recommend it to you.
8# Strike Industries AR-15 Buffer Tube
The 7-position bottom from Strike Industries was created specifically for the AR10 and AR15 but applies to other platforms as well. As an innovative addition, the buffer tube is rewarded with a characteristic ridge. The scallop reduces friction against the stock and reduces weight while maintaining the full strength of surfaces exposed to maximum stress.
If you want to make your unique build even better – take a closer look at the Strike Industries Advanced Buffer Tube with 4 color options. For the production of this buffer tube, 7075-T6 aluminum is used. Subsequent processing on machines grinds and polishes the ends and runs the thread many times. As an innovation that may surprise you, a front groove has been added for securing the buffer clip. Painstaking attention to detail turns this buffer into a piece of engineering.
All this is covered with durable anodizing of the selected color (black/red/blue /FDE). This is one of those cases where the chosen one may differ slightly from the one shown in the picture. FDE appears darker metallic and burnt like burnt bronze. Perhaps this is because aluminum has its natural grayness and absorbs some of the bright colors, leaving a matte base and a slight metallic sheen.
With an overall length of 7.28 inches, a diameter of 1.145, and a weight of 3.8 ounces, it is fully Mil-Spec AR15 compliant, compatible with Strike Industries Pit Viper stock, can operate with an adjustable SBA lock, and fits the HK416 gun shackle adapter. More precise length adjustment and 7 positions guarantee you will find your ideal tension, without hesitation on the body. The only thing is that this tube cannot work with the A5 buffer system.
We still have two pieces of news about this offer. This offer does not include a spring, end plate, or castle nut. This is replacing your standard buffer tube with a Strike Industries buffer tube (color of choice). But there is also positive news, for all the US military and those who served in law enforcement (emergency response) a pleasant discount is provided. It’s cute and we love it.
9# Timber Creek Outdoors AR 15 Mil-Spec Buffer Tube
The Timber Creek Outdoors Mil-Spec Buffer Tubing is marketed as the best addition to an AR15 or AR308 build but is also compatible with other stocks from many manufacturers. The vial is available in 9 different colors and will definitely fit your build. This component is manufactured from T6-6061 aircraft-grade aluminum using high-precision CNC machining. The end of the recess has recesses for centering over the bumper stop. The last 3 holes in the tube are gouged, presumably for the discharge of water and debris without removing the buffer tube. If our assumption is correct, this is an interesting engineering solution that shows user care.
The anodized coating is evenly distributed on both the outside and the inside of the tube. We did not find any roughness that could catch in the spring or something similar. It may be difficult to screw on the box nut for the first time, but putting it back on will smooth it out. Timber Creek Outdoors Mil-Spec Buffer Tube will work with SBA as it meets Mil-Spec standards. Accordingly, the tube is 7.25 inches long, 1.148 inches in diameter, and 3.75 ounces in weight. You will not find a castle nut, end plate, or spring in this offer. This is just a colored test tube and nothing else. But along with that, it has a good price tag and a lifetime warranty.
10# Luth-AR 9mm Carbine Buffer Assembly – Mil-Spec
Another bright offer. This time to upgrade your pistol caliber carbine. This 9mm Mil-Spec buffer tube from Luth-AR is fully equipped to integrate with a 6-position karabiner stock. It looks good and works even better with many rifles like the AR-10 or AR-15. As expected, this Mil-Spec buffer tube is made of aluminum and weighs in at 5.3 ounces. The buffer is well-finished and coated with anodized glaze. Added to this is a stainless-steel spring. Everything is designed and calculated for the use of 9×19 mm cartridges. Luth-AR attaches great importance to ensuring trouble-free reliability and security. The installation of this assembly is very simple and easy. Simply slide into any Mil-Spec lower barrel while still being compatible with the Luth-AR MBA-3/4 rifle buttstock. The kit also includes a plate retainer and retaining ring. Luth-AR has passed everything so that the buffer tube can please you and protect your new build from disappointment.
11# TRYBE Defense AR-15 Buffer Tube
TRYBE Defense loudly declares itself as a manufacturer of high-quality and affordable rifle components. This time our review includes a buffer tube for AR10 / AR15 / AR308 rifles with a stylish black finish. Two offerings are available, shock absorber with or without foam cheek pad. This is an anodized pistol shock absorber manufactured taking into account all the requirements for the reliability of weapon assemblies. This tubing is standard 7.25″ length and 1.24″ diameter suitable for a pistol or carbine. You will not find this information in the product description on the planet page, so we indicate this for our readers. If you are looking for a mod 1 shank buffer tube, do not buy this tube, it will not work for you. TRYBE Defense comes with a limited lifetime warranty and good value for money. Unfortunately, the package is reduced to only one component, so it is difficult to recommend this as a complete replacement of the lower part. It is a good replacement part with a quality finish and a black anodized finish.
12# KAK Mil-Spec Carbine AR 15 Buffer Tube Kit
Kak Industry did not want to stand aside and also joined the competition to create the best offer for the AR-15. This set for carabiner tubes meets all standards and is fully integrated with Mil-Spec. In the kit, you will find all the standard checklists that will be required when installing these lower parts. The anodized aluminum body of the 6-position tube is finished in matte black and will fit the vast majority of rifles. The silicone spring has a standard stiffness and glides well inside, especially after lubrication. If you’ve noticed the price of this kit, the richness of the package should surprise you. A standard karabiner buffer, lock nut, and endplate are added to the buffer tube and spring. That’s all you need and it is carefully added by Kak Industry. The main disadvantage of this proposal is the impressive weight of the kit. It weighs in at 9.8 ounces and we didn’t like it. Even an extra 5 ounces over the long haul turns into overwhelming pounds. This is perfectly acceptable at home, or the shooting range, but not on long hikes.
13# Tacfire AR15 Pistol Buffer Tube Kit
This is a triple proposal for a low-budget build of the AR-15 Mil-Spec pistol. The first kit added an adapter for a two-loop lanyard, the second a set of buffer sleeves for a pistol with a vertical lanyard adapter, and the third proposal was awarded the RegulAR endplate. The kits are a little heavy, but at the same time feel solid and well-crafted. The buffer cylinder is made of 6061 T6 aluminum. The entire assembly is 8 inches (L) and 13 ounces. This weight seems overwhelming, but the price says “You get what you pay for.” Tacfire pre-packaged kits include Classic Mil-Spec Gun Buffer Tube with Foam Insert, 3 Oz Buffer, Buffer Spring in Standard Carabiner Springs, Dual Loop Lanyard Adapter End Plate (Optional), and Castle Nut. There is a gasket on the buffer tube as well as a neoprene cover. This means you get a kind of “double gasket”, but the price is still very low. Of the shortcomings, we noticed 3 factors: the excess weight of the entire set, the buffer, and the spring create a noticeable noise and unreliable staining (the paint is scratched and peeled off). Otherwise, we really liked this budget proposal, and of course, we recommend it.
14# JE Machine Tech AR-15/AR10 Mil-Spec Buffer Tube
Our latest offering has many strong contenders but still surpasses them in price and quality. JE Machine Tech has created a really high-quality buffer tube without turning out their fans’ pockets! This is a one-item offer but should definitely be considered. The JE Machine Tech AR-15 / AR10 Mil-Spec 6-Position Buffer Tube is made from impact-extruded 6061 T6 grade aluminum. Smooth blackening hides full compliance with MIL-A-8625 F, type III (class 2 anodizing). The philosophy of this product is to take care of its customer. By purchasing this for little money, you will definitely be glad you could save. Having experienced this, you will be able to assess the reliability and quality of production, which means you will rejoice at the conclusion of a successful deal. And now, after a while, you become a fan of JE Machine Tech, just like us. =)
How to Choose The Right Buffer for Your AR-15? 💡
🔐 When selecting a buffer tube for your AR-15, it’s important to consider a few key factors to ensure compatibility and optimal performance. 📝Based on the results of our research, here are some factors to consider when choosing:
- ➡️ Mil-Spec vs. Commercial: Buffer tubes come in two primary types: Mil-Spec and commercial. Mil-Spec tubes have a diameter of 1.148 inches, while commercial tubes have a slightly larger diameter of 1.168 inches. It’s crucial to match the tube type with the corresponding lower receiver type to ensure a proper fit. Most AR-15s are built with Mil-Spec dimensions, so it’s often recommended to go with a Mil-Spec buffer tube.
- ➡️ Material and Construction: They are typically made from aluminum alloy. Look for tubes made from high-quality materials and robust construction to ensure durability and reliability. The tube should be capable of withstanding the recoil forces generated by your AR-15.
- ➡️ Length and Configuration: Buffer tubes come in different lengths and configurations to accommodate various stock options and shooting preferences. The two common configurations are carbine-length and rifle-length. The carbine-length tube is shorter and is compatible with collapsible stocks, while the rifle-length is longer and is used with fixed or adjustable rifle stocks. Choose a length that suits your desired stock type and shooting style.
- ➡️ Weight: Consider the weight, especially if you prioritize lightweight builds. Some options are designed to be lighter than others, which can be advantageous for shooters who require enhanced mobility and reduced overall weight.
- ➡️ Compatibility with Accessories: If you plan to use additional accessories such as adjustable stocks, cheek rests, or sling attachment points, ensure that the tube is compatible with those components. Some buffer tubes may have built-in features or attachment points for accessories, so factor that into your decision-making process.
- ➡️ Brand Reputation: Opt for buffer tubes from reputable manufacturers known for producing reliable firearm components. Brands such as Aero Precision, BCM, Daniel Defense, and VLTOR are well-regarded for their tubes and other AR-15 parts.
🔔 Additionally, familiarize yourself with any legal requirements or regulations that may apply in your jurisdiction when modifying or replacing parts of your firearm.

I recently purchased the Phase 5 Pistol Buffer Tube assembly after conducting thorough research and comparing various similar options. The Phase 5 model I chose has gained significant recognition and respect within the AR pistol build community due to its exceptional engineering and high-quality construction. One notable advantage is its outer diameter and length, which allows compatibility with several slip-on braces from SB Tactical, offering flexibility to users. I decided to invest in the Phase 5 Pistol Buffer assembly as a contingency plan amidst the legal challenges faced by pistol braces from federal entities. This particular design of a padded buffer tube is rooted in the origins of AR pistol design and has been fully endorsed by the BATF (Bureau of Alcohol, Tobacco, Firearms, and Explosives). I highly recommended this product to a close friend, who also made a purchase for the same reasons I mentioned.
I recently acquired the Strike Industries BT extension and put it to the test by firing 100 rounds, and I’m happy to report that it performed flawlessly. The B5 stock fits snugly without any noticeable wobble. To enhance its functionality, I added a Sprinco White Hot spring and a Kaw Valley tungsten powder buffer. As a result, the stock moves smoothly and securely locks into place at every position. Not only am I impressed with its performance, but I also love the aesthetic appeal. Without hesitation, I highly recommend this extension to anyone seeking an upgrade for their firearm.
The receiver extension I purchased is truly impressive. The threads are impeccably clean, and the fit and finish are superb, adding a touch of excellence to my FDE furniture setup. I am thoroughly satisfied with how it seamlessly brings everything together. Without a doubt, I’ll be considering this brand for any future builds I undertake.
I’m extremely pleased with my decision to choose the Phase 5 tube for my AR pistol build. Given the concerns I had about buffer weight and spring issues, I approached this product with caution, keeping my expectations in check. However, I’m thrilled to share that my experience at the range was flawless, firing 120 rounds without encountering a single problem. The Phase 5 tube has exceeded all my expectations, and I wholeheartedly recommend it to others.
The fit and finish of the parts are exceptional, and I couldn’t be happier. As of now, everything is working flawlessly in my pistol build. However, I believe it would be even more appealing if the tube included a QD sling attachment at the end. Nonetheless, overall, I am highly satisfied with the product’s performance.
The Aero Precision BT is an excellent choice for my AR’s when paired with the Luth MBA-1 precision stocks. Its remarkable quality surpasses any other buffer tube I have tested from different brands. When it comes to fixed stock buffer tubes, the Aero Precision is unrivaled. I have experimented with numerous buffer kits, but this one stands out as the absolute best.
It complements my Aero Precision rifle perfectly, functioning exactly as expected. I highly recommend this kit for your next build, especially if you’re constructing an AR with a fixed stock. It’s a must-have addition.
Can I interchange mil-spec and commercial-spec buffer tubes on an AR-15?
❌ In general, buffer tubes and stocks designed for mil-spec and commercial-spec dimensions are not interchangeable without adapters. The diameter difference between mil-spec and commercial-spec buffer tubes means that their corresponding stocks will also have different dimensions.
💡 However, some companies offer adapter kits that allow you to use a commercial-spec stock on a mil-spec buffer tube or vice versa.
The Spikes MS buffer (from the top picks in the article), serves as an ideal buffer for any build. Its exceptional quality is evident in its flawless fit and finish. The buffer’s numbered positions provide added convenience. I combined it with the MFT minimalist stock, resulting in an impressive aesthetic.
I recently completed a build using Spike’s upper, lower, and buffer tube as the key foundation components. These items boast top-notch quality in both material selection and manufacturing craftsmanship. Rest assured, you won’t be disappointed with Spike’s products. They consistently deliver excellence that exceeds expectations.
Having noticed some dings and scratches on my old buffer tube, I made the decision to replace it with this new one from Spikes Tactical. It’s my first experience with their products, and I must say, the build quality is exceptional. I paired it with a Hogue oversold stock on my AR10, and the combination is superb. There’s no looseness or play between the stock and buffer tube, ensuring a solid and reliable connection.
I am really impressed with the Aero Precision buffer! It provided me with the opportunity to enhance my rifle stock with a sleek and contemporary Hera stock, specifically designed to be compatible with this buffer type. The buffer’s solid spring construction significantly minimizes recoil, surpassing the performance of my previous setup.
