Frequently Asked Questions
What gas system does this barrel use? A pistol-length AR-15 gas system, matched to the 10in barrel length.
Is this barrel ready to install? Yes, it ships fully chambered and ready to install onto a compatible AR-15 upper.
Is this barrel itself an NFA item? No. This is a bare barrel under the 16-inch federal rifle minimum with no receiver included, so it is not itself a regulated Short-Barreled Rifle. Federal SBR rules only apply once it is assembled onto a complete, shouldered rifle lower without a prior approved ATF Form 1 — confirm your build configuration before assembly.
