PSA provides an update on the Sabre Mixtape Volume 2, now chambered in .338 ARC and built around the new Sabre E4 bolt system featuring a larger bolt diameter, dual ejectors, and tapered lugs for improved durability and reliability. The rifle uses the new Sabre enhanced IICAR receiver set compatible with Magpul ICAR magazines and includes a fully ambidextrous lower, Maxim CQB brace and buffer system, Radian Raptor LT charging handle, stainless 1:5 twist bead-blasted barrel, and a Sabre Plan B muzzle device. The E4 bolt is currently in final endurance testing, and once complete, the Mixtape Volume 2 will move into full production, with more updates coming ahead of SHOT Show.
