AR-15 M4 Classic Upper Carbine length 16" Barrel 5.56 NATO Twist 1/8 with M-16 Bolt Carrier Group and Charging Handle

AR-15 M4 Classic Upper Carbine length 16" Barrel 5.56 NATO Twist 1/8 with M-16 Bolt Carrier Group and Charging Handle.

The boxes are marked as BLEM and may have some small cosmetic blemish, but I have yet to find any. Certainly nothing effecting the function..

The 1:8 twist barrel is the most versatile and the perfect option for 16" carbine AR-15's. This twist rate can comfortably stabilize up to an 80-grain projectile while still providing enough flexibility for shooters to use lighter ammo for matches like 3-Gun.

Barrel: Phosphate coated (Packetized) 4150V Chrome Moly steel. Chambered in 5.56 NATO, with a 1:8 twist, M4 barrel extension, and a carbine-length gas system. Barrel is finished off with a standard handguard, F-Marked gas sight base, and A2 flash hider.

Upper: Forged 7075-T6 A3 AR upper is machined to MIL-SPECS and hard coat anodized, features a forged upper receiver. These uppers are made for us right here in the USA by a mil-spec manufacturer.

Bolt: Full-auto profile bolt carrier group. Milspec Carpenter No. 158® steel bolt. Gas Key Hardened to USGI Specifications, Fastened with Grade 8 screws, and Staked Per Mil-Spec.
