The definition of precision.

The PRS GEN3 is a field precision stock for AR15/M16 and AR10/SR25 platforms, featuring toolless 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.

Mounts to rifle-length receiver extension tube without A2 spacer but will also accommodate Mil-Spec sized M4 Carbine and many A5-length tubes with standard Castle Nuts and End Plates (not included) Made in the USA.
