Would not recommend

The barrel I received seems to be out of spec. Barrel was visibly canted to one side once installed in a BCM upper receiver with a BCM FF handguard. Installing the barrel on a different BCM upper yielded the same result. In order to get the rifle to zero at 25 yards, windage had to be set to the maximum leaving little room for adjustment after that.

Not a good barrel

The barrel I received seemed to be out of spec. I installed the barrel in a BCM upper with BCM handguard, and the barrel was obviously canted to one side. I installed the barrel in a different upper, and the result was the same. The barrel was canted enough that windage had to be set to its maximum on one side.
