The Seekins Precision AR15 .300 BLK 8" Barrel is purpose-built for shooters who want maximum performance in a compact, maneuverable platform without sacrificing precision. Machined from high-quality steel and finished in a durable black coating, this barrel features an 8-inch length optimized for the .300 Blackout cartridge, delivering reliable ballistic performance whether running subsonic or supersonic loads. The 1:8 twist rate ensures consistent stabilization across a wide range of bullet weights, while the M4 contour balances strength with reduced weight for fast handling. A 5/8"x24 threaded muzzle allows easy attachment of suppressors or muzzle devices, making this barrel an excellent choice for suppressed SBR builds or compact AR configurations where accuracy, reliability, and craftsmanship matter most.
