Frequently Asked Questions

What are the key differences between Mil-spec and Commercial buffer tubes for AR platforms?

Mil-spec buffer tubes have a smaller outer diameter of 1.14 inches at the stock end, while commercial buffer tubes are slightly larger at 1.17 inches. This difference is crucial for ensuring a proper fit when selecting a butt stock.

What are the legal requirements if I put a stock on an AR9 with a barrel under 16 inches?

If you equip an AR-style firearm with a barrel under 16 inches with a butt stock, it is legally classified as a Short Barreled Rifle (SBR) and must be registered with the ATF, which involves a tax stamp and paperwork.

What grip angle is recommended for AR9 PCCs, and why?

A pistol grip angle between 15 and 30 degrees is often recommended for AR9 PCCs. This angle can help align your wrist for a more secure shoulder brace and facilitate easier movement while shooting.

How do pistol braces differ from stocks on AR pistols or PCCs?

Pistol braces are designed to attach to the forearm, providing stability for shooting larger pistols or short-barreled rifles without the legal classification of an SBR. They offer an alternative to traditional butt stocks for firearms with barrels under 16 inches.
