Bear Creek Arsenal 20" 6.5 Grendel Type II AR 15 Barrel

The Bear Creek Arsenal AR-15 Barrel is a 20" heavy barrel profile made of 416R stainless steel. rifle length gas system with a 1:8 twist rate and is chambered in 6.5 Grendel Type II. All 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.

The difference between a Grendel type 1 and type 2 is a type 1 was the original design using a compound throat and a 7.62x39 bolt and the type 2 has a parallel throat and has a different headspace so a type 2 bolt is required.
