Colt LE6921 SBR 5.56 NATO 14.5" 30-Round Rifle

The Colt LE6921 is a semi-automatic AR-15 rifle with a 14.5-inch barrel, configured as a short-barreled rifle (SBR) under the National Firearms Act. It is built around an M4-profile, chrome-lined barrel with a 1:7 twist rate suited to 5.56 NATO projectiles weighing 55 to 77 grains. The chrome lining in the bore and chamber is intended to resist corrosion and wear under high round counts.

The rifle has a matte black finish, a muzzle compensator, and a Magpul MBUS flip-up rear sight paired with an A-post front sight. The 6-position collapsible stock adjusts length of pull. The package includes one 30-round magazine. Because it is an NFA-regulated SBR, the transfer requires Form 4 approval and payment of the $200 tax stamp.
