The BCA AR-15 Complete Upper Assembly has an 16" heavy barrel made out of 4150 chrome moly vanadium steel with a parkerized finish, a 1:24 twist rate and Carbine Length Gas System. The build includes a standard handguard rail, an M4 flat top forged upper receiver with forward assist, a proprietary bolt carrier group, birdcage flash hider and a charging handle. It is chambered in .450 Bushmaster and machined with a single feed ramp in the barrel extension.

All Finished Barrels go through a 100% Inspection Process.

Inspections Equipment includes CMMs and Air Gauges for the Bores.

BCA's expectations is that our Barrels, 16 inch or longer, will hold a 1.000" MOA at 100 yards with appropriate ammo and shooting techniques.
