The Seekins Precision Bbl 8" 300BLK Sts Blk is a match-grade stainless steel barrel built for AR-15 pistols and short-barreled rifle builds that demand consistent accuracy. Precision CNC machined from premium 416 stainless steel and finished in a non-glare bead-blast ArmorBlak coating, this 8-inch threaded barrel is optimized for the 300 AAC Blackout cartridge with 5R rifling and a 1:7 twist rate.
This compact barrel is ideal for building a maneuverable AR platform tailored to range use, training, or home protection roles where reliability and controllable recoil matter. The pistol-length gas system and .750" gas block journal with alignment dimple simplify setup and tuning, especially for suppressed configurations. Seekins Precision is known for tight tolerances, rigorous inspection, and thoughtful design that give shooters confidence in every shot.
