Frequently Asked Questions
Can I install this barrel on a standard AR-15 lower receiver?
Due to its 10.5" length, this barrel is subject to NFA/ATF regulations. It may only be used on a lower receiver that is a registered SBR, registered Machine Gun, or configured as a pistol (with a pistol brace or no stock). Pairing this barrel with a standard rifle lower receiver and a stock is prohibited by federal law unless the lower is properly registered as an SBR with the ATF. Always ensure your build is compliant before assembly.
What bullet weights does the 1:7 twist rate stabilize best?
The 1:7 twist rate is optimized for heavier 5.56 NATO and .223 Rem projectiles in the 62–77 grain range, including M855 green tip and Mk262 ammunition. It will also reliably stabilize lighter 55-grain loads, making it a versatile choice for a wide variety of training and defensive ammunition.
Is a gas block included with this barrel?
No, a gas block is not included with this barrel. The .750" gas block journal is compatible with standard low-profile or adjustable gas blocks in that diameter, which are widely available and easy to source separately. When building your pistol or SBR, ensure you select a gas block rated for carbine-length gas systems to match this barrel's port location.
