Lightweight, compact accuracy with a quality stainless barrel.
Lots of AR pistols come with carbon steel barrels. Those barrels do just fine, but 416R stainless can provide significantly better accuracy – and easier cleaning and maintenance to boot. This 10.5″ AR kit provides just that, paired with a prebuilt upper, M16 BCG, and lower parts kit.
Note: Due to ATF rule 2021R-08F, any pistol with a stabilizing brace is considered a short-barreled rifle (SBR), and is therefore considered a National Firearms Act item requiring a federal tax stamp.
