This AR-Stoner carbine length upper features a mil-spec bolt carrier group, phosphate finish, A2 fixed front sight and a government profile barrel. The A3 upper will attach to virtually any standard AR-15 lower receiver and comes complete with charging handle, forward assist, ejection port cover, bolt and bolt carrier assembly. With a 1 in 7″ twist, the 16″ barrel provides outstanding accuracy with a wide range of projectiles. Supplied without a rear sight, this upper is a great platform for a red dot sight or iron sights (both sold separately).
The AR-STONER Carbine Kit also includes a M4 mil-spec 6-position stock assembly. The buffer tube is machined from 6061-T6 aluminum and given a hard coat anodized finish to withstand years of abuse. The 6-position telescoping stock features a built-in sling swivel to mount your favorite rifle sling.
Included in the Carbine Kit is the AR-STONER Lower Parts Kit which includes everything needed to build a complete lower receiver, except a stripped lower receiver. All parts are made to standard military specifications.
