The PRS GEN3 is a field precision stock for the AR15/M16 platform, featuring tool-less length of pull and cheek piece height adjustment, 3/4 of an inch longer than an A2 stock when collapsed, 2 inches longer than an A2 stock when extended. 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 (6-position adapter not included). 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.
