The AR-15 Barrel is a 20" Heavy barrel made out of 416R Stainless steel, a 1:7 twist rate and a rifle length gas system. The barrel is chambered in .22 Arc.
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.
