The Wilson Combat 8" 300 Blackout match-grade barrel is purpose-built for AR-15 short-barreled rifle builds where compact size and close-quarters capability matter. Machined from 416R stainless steel and finished with a durable bead blast, this SBR tactical profile barrel ships with a 5/8x24 threaded muzzle ready for suppressors or muzzle devices. Whether you're running subsonic loads through a can or pushing standard rounds downrange, this barrel's 1:7 twist stabilizes the full range of 300 Blackout ammunition.
Wilson Combat engineered this barrel around the pistol-length gas system standard, so you'll have no trouble sourcing compatible parts from the wider AR aftermarket. The .750-inch gas journal accepts most gas blocks without fitment hassle, and the M4-style feed ramps ensure reliable feeding across quality ammunition. This is a no-compromise component for builders who want match-grade accuracy in a fighting-length package—the kind of precision barrel you'd expect from a shop that's been building rifles for serious shooters since day one.
Before you assemble your SBR, remember that federal law requires NFA registration on Form 1; you'll want to ensure your lower is registered before you finalize the build. Once it's legal and locked in, you've got a stout, compact 300 Blackout that handles both subnose and full-power loads with the accuracy Wilson Combat is known for.

Yes. The 5/8x24 threaded muzzle is the industry standard for suppressor attachment. This barrel is specifically optimized for use with suppressors and subsonic 300 Blackout loads.
This barrel is built around a standard pistol-length gas system with a .750-inch gas journal, which is compatible with the vast majority of aftermarket AR gas blocks and components.
No. As a barrel component alone, it is not an NFA item. However, once you assemble it into a complete short-barreled rifle (barrel plus registered receiver), that rifle must be registered on ATF Form 1 before it is legal to possess.
The 1:7 twist is appropriate for the full range of 300 Blackout ammunition, including both subsonic and standard pressure loads.
