The PRS GEN3 is a field precision stock for AR15/M16 and AR10/SR25 platforms featuring tool-less length of pull and cheek piece height adjustment. 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 but will also mount to many mil-spec carbine and A5-length tubes*. Includes a cant/height-adjustable rubber butt-pad and rotation-limiting QD sling swivel cups as well as M-LOK slots on the bottom for rear monopod mounting.
