The Seekins Precision BBL 10.5" 300BLK BLK barrel is a compact, match-grade option for AR builders who want reliable performance from a short 300 Blackout platform. Precision CNC machined from high-quality 416 stainless steel and finished in a non-glare ArmorBlak coating, this threaded 10.5" barrel is designed as a true drop-in upgrade for mil-spec upper receivers.
With 5R button rifling, a 1:7 twist rate, and a pistol-length gas system, this barrel is optimized for both subsonic and supersonic 300 Blackout loads, making it well suited for range use, training, and hunting where a shorter, suppressor-ready setup is preferred. The integrated gas block alignment dimple simplifies installation with a .750" gas block, reflecting Seekins Precision’s focus on practical details and consistent craftsmanship.
