Parts🔑

Bolt 🔩: The bolt is a cylindrical component that houses the firing pin, extractor, and other essential elements. It locks into the barrel extension, ensuring proper chambering and extraction of the cartridge.
Carrier 🚀: The carrier is a larger component that holds the bolt and reciprocates within the upper receiver. It transfers the energy from the gas system to cycle the action of the rifle.
Firing Pin 🔫: The firing pin is a small, cylindrical pin housed within the bolt. When struck by the hammer or striker, it impacts the primer of the cartridge, igniting the propellant and firing the round.
Extractor 💥: The extractor is a claw-like mechanism located on the bolt that engages the rim of the cartridge case during extraction. It pulls the spent case out of the chamber and ejects it from the firearm.
Ejector ⬅️: The ejector is a spring-loaded plunger located within the bolt that interacts with the cartridge case during the ejection process. It forcefully ejects the spent case out of the ejection port.
Gas Key 🔐: The gas key is a small, rectangular component that attaches to the carrier. It receives gas from the gas tube and directs it into the carrier to cycle the action. It is secured with screws and properly staked to ensure a gas seal.
Cam Pin ⚙️: The cam pin is a cylindrical pin that connects the bolt and carrier together. It fits into corresponding cam pin slots in the upper receiver, allowing the bolt to rotate and lock into the barrel extension.
Firing Pin Retaining Pin 🔒: The firing pin retaining pin is a small, cylindrical pin that secures the firing pin within the bolt. It prevents the firing pin from moving forward until struck by the hammer or striker.
Gas Rings 🔗: The gas rings are three small, split rings located on the carrier. They help seal the space between the carrier and the walls of the upper receiver, ensuring proper gas pressure for reliable cycling.
Bolt Cam Pin Hole 🔩: The bolt cam pin hole is a cylindrical hole in the bolt that allows the cam pin to pass through, connecting the bolt and carrier together.

Hello everyone,
I have a question: Are there any differences between a 65 Grendel bolt carrier and a regular bolt carrier? Can I replace the bolt on my 556 BCG with a 65 Grendel bolt and use it without any problems?
I am also wondering if I could use one of the “adjustable” bolt carriers in my rifle.
Thank you.

    The answer to your question is yes, there are some differences between a 65 Grendel bolt carrier and a regular 5.56 bolt carrier.

    🟡 The most significant difference is that the 65 Grendel bolt has larger dimensions and lugs than a regular 5.56 bolt carrier, meaning that it won’t fit into a standard-sized 5.56 BCG.

    🟡 Additionally, the 65 Grendel BCG is designed to handle higher pressures than the standard 5.56 BCG, so it’s not recommended to swap out the bolts from one to another without further research or specialized tools.

    🟨 In short, no, you cannot just swap out the bolts on your 5.56 BCG and expect it to work properly with a 65 Grendel round – you’ll need to purchase an appropriately sized bolt carrier group in order for the two rounds to be compatible with each other.

      the carrier remains the same, but the bolt has been replaced. Although JP has been known to manufacture superior Grendel bolts, Toolcraft has resolved their extractor problems and now produces reliable bolts.

        As far as I know, the carrier remains the same and only the bolt is different. Although I’m not an expert on this topic, I don’t see any reason why you couldn’t use the Grendel bolt with one of your other carriers. Maybe someone with more experience can confirm this.

          As mentioned by others, any BCG for 5.56 should be compatible. However, some bolts may have extractor issues. If you have already purchased a bolt for your 6.5, it is still advisable to buy the JP enhanced extractor in case reviews of the bolt indicate any extractor issues.

                have decided to build a 6.5 Grendel and am considering the BA BCG because of my positive experience with their barrels. I have already purchased a BA barrel to start with. Should I be cautious of anything when matching the BCG with my barrel?
