The following is a brief look at the following Bear Creek Arsenal Barrel:
Model: B308RMW20110(M)

Caliber: .308 Winchester
Rifling Twist Rate: 1:10

Groups shown were shot from a concrete bench, with front and rear sandbag rests.

Barrel was cleaned before shooting. And after initial sight-in.
Build notes:
-Barrel was free floated.
-Barrel extension and upper receiver had a tight interference fit.
-Barrel nut was torqued and loosened 3x before final torque value.
-Gas block was aligned properly, and taper pinned.
-Muzzle device used a crush washer, but was pre-crushed before installation so that it could be installed only 1/16th of a turn past hand tight.
Lower receiver has a RA-140 Single stage trigger that breaks right at 4lbs.
