6.5 Grendel Barrel Samurai Firearms
6.5 Grendel Barrel Samurai Firearms
6.5 Grendel — 16" Mid-Length Barrel Finished Sabre Defence rifled blanks — QPQ nitrided, chamber-polished and assembled to exacting standards. Finished • QPQ Nitride 16" Mid-Length Gas Limited Quantity 5/8x24 Thread From an exclusive cache of Sabre Defence blanks, Samurai Firearms and H&M Metal Processing completed these barrels the right way: nitride first, then chamber polish and extension installation. The result is a durable, repeatable 16" mid-length barrel optimized for heavier 6.5 Grendel bullets. Key Specs Caliber6.5 Grendel Twist1:7.5 Length16" Mid-Length Material4150 Steel FinishQPQ Nitride (H&M) ProfileLight HBAR Thread5/8x24 Weight~2.0 lb Barrel Only — Bolts or complete carrier groups available as optional upgrades Requires .136 (Type 2) 6.5 Grendel bolts. Why this barrel matters Every step in the finishing sequence matters. These blanks were QPQ nitrided by H&M first—then chambers were polished and extensions installed. That sequence prevents distortion, preserves headspace integrity, and delivers consistent accuracy over thousands of rounds. Light HBAR profile keeps weight down while maintaining rigidity where it counts. Proper process: nitride → polish chambers → install extensions — done in the correct order. Durability: QPQ nitride offers superior wear and corrosion resistance under high round counts and harsh environments. Optimized for heavy bullets: 1:7.5 twist gives excellent stability with heavier 6.5 Grendel projectiles. Ready for build: dimpled for gas block and laser-caliber marked for easy identification during assembly. Finished 16" barrel with mid-length gas system. Extensions installed after nitride; chambers polished for long-term reliability. NOTE: This listing is for the barrel only. Bolts and complete carrier groups are available separately — contact for upgrade options. What’s included Finished 16" mid-length barrel (from Sabre Defence blanks) QPQ nitride by H&M Metal Processing Dimpled for gas block, laser caliber mark Extensions installed after nitriding; chambers polished Bolt & compatibility reminder This barrel requires .136 (Type 2) 6.5 Grendel bolts. Verify bolt spec before assembly — using the correct bolt type preserves timing, extraction, and safety. Proven finish & workmanship H&M Metal Processing — a trusted partner for 15+ years — performed the QPQ nitride process under controlled conditions. Samurai Firearms and H&M followed gunsmithing best practices: nitriding first avoids heat-induced distortion during extension installation and chamber work. Polished chambers reduce brass adhesion and improve extraction consistency. Performance highlights Repeatable accuracy with consistent headspace Excellent corrosion and wear resistance Optimized for heavier-for-caliber projectiles Limited availability These barrels were rescued from a limited Sabre Defence stock and professionally finished in small batches. Quantities are strictly limited — once sold, these exact barrels won't be duplicated. Limited quantities — ready for immediate shipping. For builders who demand proper process and proven materials — this is a finished 16" 6.5 Grendel barrel built the right way. Inquire for bolt or carrier upgrade options and expedited shipping.
