With solid adjustments for length of pull and cheek piece height via aluminum detent knobs, the PRS GEN3 (Precision Rifle/Sniper) stock provides a stable interface and is intended for semi-automatic sniper or varmint type rifles. Offering a nearly universal fit, it is optimized for rifle-length receiver extensions (which are not included) but will also mount to many mil-spec carbine and A5-length tubes with standard castle nuts and end plates (which are not included). Includes a cant/height-adjustable rubber butt-pad and rotation-limiting QD sling swivel cups as well as M-LOKĀ® slots on the bottom for rear monopod mounting.
