Christensen Arms CA15-G2 Features The Christensen Arms CA15-G2 uses a 416R stainless steel barrel wrapped in AeroGrade carbon fiber a construction method that sheds significant weight compared to a traditional steel barrel while maintaining the stiffness needed for consistent accuracy. A stainless steel flash hider paired with a match chamber and a 1/2x28 standard thread pitch rounds out a barrel system built for both suppressor use and reduced muzzle flash. The direct impingement gas system cycles through a G2-style bolt carrier group finished in black nitride for smooth reliable operation. Billet 7075 aluminum upper and lower receivers give the CA15-G2 a rigid foundation with an integrated undercut trigger guard for improved ergonomics during extended shooting sessions. The match-grade trigger breaks crisply between 3.5 and 4.5 lbs giving shooters the consistency needed for precision work at distance. A 14.75 slim-line carbon fiber M-Lok handguard keeps the rifle s forend lightweight while providing ample real estate for accessories and the adjustable BCM Gunfighter stock lets shooters dial in their length of pull for a personalized fit.
