Compatibility Notice: This is a RemAge-style barrel designed for Faxon FX7 actions as well as most OEM Remington 700 short action receivers and similar actions using RemAge-style installation practices. Always verify receiver thread specs, tenon requirements, and proper headspacing before installation.
The Faxon RemAge Style Gunner 12" 8.6 Blackout SAAMI Barrel is purpose-built for compact, suppressed bolt-action platforms that demand extreme ballistic performance from the 8.6 BLK cartridge. The aggressive 1:6 twist rate is essential for stabilizing long, heavy 8.6 BLK projectiles and maximizing rotational energy, especially in subsonic and suppressed configurations.
Machined from 416-R stainless steel at Faxon’s Cincinnati facility, each barrel is fully stress relieved, air-gauge tested, magnetic particle inspected, and finished with a durable QPQ salt bath nitride treatment inside and out. A recessed target crown ensures consistent accuracy shot-to-shot. Proudly American-made by a family-owned company in Greater Cincinnati, Ohio.

PLEASE NOTE:
8.6 BLK is now SAAMI certified, standardizing chamber and cartridge dimensions (including headspace) for enhanced safety, consistency, and ammunition interchangeability across manufacturers.
The primary changes with SAAMI certification include formalized headspace dimensions and support for moderate twist rates (compared to earlier aggressive designs), promoting greater versatility with a wide range of projectiles—making this RemAge-style 1:6 twist barrel an excellent fit for balanced precision in both subsonic and supersonic applications.
