Why This Barrel

The 11.5" length strikes an excellent balance for modern tactical and sporting applications. It's short enough for close-quarters work and vehicle operations, yet long enough to maintain velocity and reliability with standard 5.56mm ammunition.

The button-broached rifling process delivers consistent accuracy while the 1-7 twist rate stabilizes a wide range of bullet weights from 55-grain varmint rounds through heavier 77-grain match ammunition.

Build Compatibility

This barrel is a direct fit for standard AR-15 platforms. The M4 feed ramp ensures reliable feeding with both mil-spec and commercial magazines. The .750 gas block diameter accommodates most quality adjustable gas blocks for tuning your specific setup.

The 4150 chrome moly vanadium construction provides the durability and heat resistance you need for sustained fire without premature wear.
