The Wilson Combat 300 AAC Blackout 1-7 twist 11.3" barrel is a purpose-built component for AR-15 short-barreled rifle builds optimized around one of modern shooting's most versatile intermediate cartridges. If you're assembling an NFA-registered SBR, this barrel delivers the compact footprint and precision engineering Wilson Combat is known for, with a twist rate specifically chosen to stabilize a wide range of .300 Blackout loads—from supersonic to subsonic ammunition. The 11.3" length positions this barrel in the sweet spot for sound suppressor integration and handy close-quarters handling without sacrificing ballistic performance.
Built from 416R stainless steel, this barrel features M4-style feed ramps and comes threaded 5/8x24 at the muzzle, the industry standard for .300 Blackout suppressors. The .750-inch gas journal accommodates a broad selection of aftermarket gas blocks, giving you flexibility in your build. A standard pistol-length gas system keeps your platform reliable and compatible with common AR components. Wilson Combat barrels are machined to tight tolerances and demand the same precision and craftsmanship you'd expect from a complete rifle—not surprising from a company with serious competition and duty-gun heritage.
This is a component, not a complete firearm. Building a short-barreled rifle requires registering your lower receiver with the ATF on a Form 1 before assembly—a critical legal step. Once registered, you have a compact, suppressor-ready platform ideal for home defense, short-range hunting, or serious close-quarters work. The 1-7 twist is engineered to stabilize heavier subsonic rounds that define the cartridge's appeal, making this barrel a natural choice if you plan to run suppressed.
