How to tell if buffer tube is mil spec?

There are a few ways to determine if a buffer tube is mil-spec.

1. One way is to measure the outside diameter of the buffer tube. The standard size for a mil spec buffer tube is 1.146 inches.

2. Another way to tell if a buffer tube is mil spec is by measuring the wall thickness. The standard wall thickness for a mil spec buffer tube is 0.093 inches.

3. You can also check to see if the buffer tube has been Mil-Specified by looking for markings on the tube itself. Buffer tubes that have been Mil-Specified will typically have markings that indicate so, such as “Mil-Spec”.

Mil-spec buffer tubes are typically made from 7075 T6 aluminum, have a hard coat anodized finish, and have grooves cut into them for the installation of stock spacers. They also have a reinforced shoulder for increased strength and durability. Many lower receivers are also made from 7075 T6 aluminum, so it’s important to make sure that your buffer tube matches your lower receiver in terms of material type and finish.

If you’re not sure whether or not your buffer tube is mil-spec, you can check by measuring its outer diameter. The dimensions of a mil-spec buffer tube are 1.148″ (width) x 1.168″ (length). If your buffer tube falls within these dimensions, then it is mil-spec.

There are a few different types of buffer tubes, but the two most common are mil-spec and commercial. Mil-spec buffer tubes are made to stricter standards and are typically used by military and law enforcement personnel. Commercial buffer tubes are less expensive and are designed for use in civilian applications.

Buffer tubes can be made from a variety of materials, but the most common material is aluminum. Mil spec buffer tubes are manufactured to stricter tolerances than commercial buffer tubes and are often found on AR-15 rifles. They are typically machined from solid aluminum billet and have a hard coat anodized finish for durability. Most milspec buffer tubes also have a ridged surface for better grip when installing or removing the buttstock.

The Mil-Spec buffer tube has been designed to the precise dimensions laid out by the military, ensuring that your AR-15 will function flawlessly with all types of ammunition. It is also machined from a high-quality aluminum alloy, providing superior strength and durability. So if you’re looking for a buffer tube that can handle anything you throw at it, be sure to go with the Mil-Spec option.

There are a few ways to tell if a buffer tube is mil spec. The easiest way is to look at the markings on the tube. If it has “MIL-SPEC” or “STANAG 4694” stamped on it, then it’s mil spec. The other way to tell is by weight. Milspec tubes are typically made from a heavier gauge metal than commercial tubes, so they will be slightly heavier in weight.
