    The Magpul PRS (Precision Rifle/Sniper) – AR15/M16 Model is a drop-in, precision-adjustable butt stock for rifles with A1/A2 fixed stocks. Designed to offer the fine-tuned, customized feel of a precision target stock, the PRS is adjustable for both comb height and length-of-pull without sacrificing the durability necessary to withstand the operational environment. Compared to the A2 stock, the PRS can shorten LOP by .25" or extend it by .75" as well as provide three-quarters of an inch of comb height adjustment. Machined aluminum adjustment knobs feature positive-locking click detents to maintain position under recoil and allows easy, tool-less adjustments by simply rotating the knobs. Aluminum butt-plate and alloy steel adjustment shafts provide stability and strength to withstand severe impact conditions. Rubber butt-pad offers positive shoulder purchase to prevent slippage for optimal accuracy even with body armor or modular gear. Bottom Picatinny-type rail allows for monopod use, additional sling mounts or storage. Stock includes all mounting hardware for A1/A2 type rifles with fixed stock.

    Great look of od green

    Great look of od green and feels like great quality, not that cheap plastic type feel. Definitely recommend. A1 a2 buffer tube required.

    awesome piece, great quality.

    Only complaint is that the cheek rest doesn't rise as high as you'd think nor does the back come out as far as some may need. Well worth the price and is on 2 of my rifles.
