The MOE Rifle Stock (Magpul Original Equipment) is a drop-in replacement for AR15/M16 A1 and A2 rifle stocks utilizing the standard rifle-length receiver extension (buffer tube). Designed as a basic upgrade, the stock features integral 1.25″ sling loop, optional dual-side front and rear QD mounting points, replaceable anti-slip rubberized butt-pad, and internal storage compartment accessible through the rear storage door. NOTE: The MOE Rifle Stock is a direct replacement for an A1 or A2 fixed stock. Fitting to a carbine with a collapsible stock will require a rifle-length receiver extension tube, rifle buffer and spring (not included). Made in U.S.A.
