Frequently Asked Questions
Is an 11.5" barrel legal to use in a standard AR-15 rifle configuration?
An 11.5" barrel on a rifle with a standard stock requires an NFA Short-Barreled Rifle (SBR) tax stamp and registration. However, this barrel is commonly used in AR pistol builds with a pistol brace, which does not require NFA registration in most jurisdictions. Always consult current federal and local regulations before configuring your build.
What bullet weights does the 1/7 twist rate stabilize best?
A 1:7" twist rate is optimized for heavier projectiles in the 62–77 grain range, including popular loads like the M855 62gr green tip and 77gr match-grade bullets. It will also adequately stabilize lighter 55gr projectiles, making this barrel versatile for both range training and defensive use.
Do I need any special components to complete my upper with this barrel?
This barrel uses a standard carbine-length gas system, so you'll need a carbine-length gas tube and a compatible low-profile gas block. It features standard M4 feed ramp cuts and a 1/2x28 threaded muzzle, making it compatible with the vast majority of AR-15 upper receivers, BCGs, handguards, and muzzle devices on the market.
