The Seekins Precision Havak Element M3 .22 Creedmoor 20" Carbon Fiber Barrel is a factory replacement and caliber-conversion barrel assembly designed for the Havak Element M3 quick-change barrel system. Featuring a 416R stainless steel core wrapped in carbon fiber to minimize weight without sacrificing rigidity, this barrel is machined to match-grade tolerances with a 1:8 twist rate and 5/8x24 threaded muzzle, dropping into any Element M3-compatible action without specialized tools using Seekins' open-source headspace and tenon specifications.
