The BCA AR-15 Barrel is an 18″ heavy profile barrel made of 4150 chrome moly vanadium steel with a parkerized finish, and a 1:24 twist rate. The barrel is chambered in .450 Bushmaster and machined with single 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 are that our Barrels, 16 inches or longer, will hold a 1.000″ MOA at 100 yards with appropriate ammo and shooting techniques.
