The BCA AR-15 Barrel is a 16″ M4 contour profile barrel made of 4150 chrome moly vanadium steel with a parkerized finish, a carbine length gas system with a 1:8 twist rate. The barrel is chambered in .300 blackout and machined with .300 blackout 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.
