The ACE-R is powered by Retay’s Straight Line Inertial Transfer System, the patented Inertia Plus Bolt Rollover Torsion Spring Action, and the Dead Straight Deep-Bore Drilled Barrel for maximum performance. It offers on-target, no-float aiming and Retay’s Out of the Box Optimization Factory-Lengthened Forcing Cone. The ACE-R leads the way with the AIRY Pad-a next-generation recoil pad that reduces felt recoil by up to 30%.
