Details

The BCA AR-15 Barrel is a 7.5" M4 contour barrel profile made of 4150 steel with a black nitride finish. It has a 1:9 twist rate and is chambered in .223 Wylde.

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.

BCA DOES NOT recommend using steel cased ammo in our Assemblies or Rifles.
