Magpul PRS GEN3 Precision-Adjustable Stock for AR15 & AR10
The Magpul PRS GEN3 Precision-Adjustable Stock for AR15 & AR10 is a heavy-duty precision rifle stock built for stable, repeatable shooting positions. It uses machined aluminium adjustment knobs with positive locking detents for tool-free length-of-pull and comb-height adjustment, while its anti-slip rubber butt-pad adjusts for height and cant to help tailor rifle fit.
Designed for AR15/M4 and AR10/M110 platforms, the PRS GEN3 mounts directly to standard rifle-length receiver extensions and can also accommodate many Mil-Spec carbine and A5-length buffer tubes. The stock includes front and rear rotation-limited QD sockets, a reversible 1.25-inch sling loop, and M-LOK slots on the underside for compatible accessories or monopod mounting.
