The Odin Works 16.1" Medium Profile 300 Blackout Barrel is a high-quality stainless steel barrel built for shooters who want precision and reliability in a short-range, subsonic-ready platform. Whether you're building a 300 Blackout AR-15 for hunting, suppressed shooting, or tactical applications, this barrel gives you the foundation for a dependable, accurate rifle. The 416R stainless steel construction and hand-lapped finish ensure tight tolerances and consistent performance, while the included adjustable gas block lets you dial in reliability with your chosen ammunition—crucial for a cartridge that spans both supersonic and subsonic loads.
At 16.1 inches, this medium profile barrel strikes a practical balance between velocity, handling, and weight. The 8-twist rifling is optimized for 300 Blackout projectiles, and button-rifled construction provides excellent accuracy potential. M4 feed ramps ensure smooth chambering, while the 5/8-24 threading accommodates standard muzzle devices and suppressors. Black nitrided finishing protects against corrosion and gives the barrel a clean, professional appearance that matches modern AR builds.
Odin Works barrels are hand-finished to tighter tolerances than mass-produced alternatives, and this one arrives ready to integrate into your upper—just bolt it in and start building. If you're assembling a 300 Blackout upper for hunting deer or hogs, running subsonic rounds through a can, or rounding out a versatile AR platform, this barrel delivers the accuracy and durability that serious shooters expect.

This is a direct-fit 300 Blackout barrel for AR-15 platforms. The 5/8-24 muzzle threading works with standard suppressors and muzzle devices. You'll need an AR-15 upper receiver and bolt carrier group chambered in 300 Blackout to complete the build.
Yes. The included adjustable gas block allows you to tune the rifle for reliable cycling across different ammunition types—supersonic loads and subsonic rounds—so you can match your setup to your ammunition and use case.
No. The barrel features 5/8-24 threading, which is the standard 300 Blackout muzzle thread pitch, so it's ready to accept any compatible suppressor or muzzle device you choose, but these are sold separately.
The 8-twist rifling is specifically optimized for 300 Blackout projectiles across the typical weight range used in the cartridge. This twist rate provides reliable bullet stabilization for both supersonic and subsonic loads.
