The BCA AR-10 Barrel is a 20″ SOCOM profile barrel made of 4150 chrome moly vanadium steel with a parkerized finish, a rifle length gas system with a 1:10 twist rate. The barrel is chambered in .308 and machined with AR-10 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.
