The BCA AR-15 Barrel is a 10.5″ M4 contour profile barrel made of 4150 chrome moly vanadium steel with a black nitride finish, a carbine length gas system with a 1:7 twist rate. The barrel is chambered in 5.56 NATO and machined with M4 feed ramps 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.
