Details

The BCA AR-15 Barrel is a 20" heavy barrel profile made of 416R steel with a stainless steel finish. It is spiral fluted with a 1:8 5R twist rate and is chambered in .223 Wylde.

5R is an improvement over conventional rifling by changing the shape and configuration of the lands and grooves. Conventional rifling consists of either 6 or 4 symmetrical lands and grooves; however, in a 5R barrel, the lands and grooves are opposite of each other and sloped.The improvement reduces projectile deformation as it passes through the bore during the firing sequence and the projectile stays uniform instead of squeezing material on opposite side grooves. Hence, the more uniform projectile, the better the accuracy.

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.
