MAGPUL AR-15/308 AR PRS GEN 3 PRECISION STOCK ADJUSTABLE RIFLE LENGTH

Adjustable for length of pull and cheek piece height via aluminum detent knobs, the PRS GEN3 (Precision Rifle/Sniper) stock is intended for semi automatic sniper or varmint type rifles. It installs on rifle-length receiver extensions as well as mil-spec and A5 length carbine receiver extensions and includes a cant/height-adjustable rubber butt-pad and rotation-limiting QD sling cups as well as M-LOK slots on the bottom for rear monopod mounting.

FEATURES

  • Mounts to rifle-length receiver extension tube without A2 spacer, but will accommodate mil-spec sized M4 Carbine and many A5-length tubes with standard Castle Nuts and End Plates (not included)
  • Enhanced strength butt-plate withstands severe impact and recoil up to .50 BMG
  • Rubber butt-pad provides positive should purchase to prevent slippage and is adjustable for both cant and height
  • Machined aluminum LOP and Cheek Piece adjustment knobs with positive locking click detents
  • Steel adjustment shafts finished with melonite for wear and corrosion resistance
  • All aluminum components finished with MIL-A-862F, Type III, Class 2 hard coat anodizing
  • Bottom M-LOK slots provide additional sling mounting possibilities for attaching 1913 picatinny railes for use with a monopod
  • Sling Mounts: Front & Rear rotoation-limited QD sling swivel mounts. Rear mount 1.25" aluminum sling loop (left side reversible)

NOTE: Due to the wide variety of designs and dimensions of carbine receiver extensions as well as the associated mounting hardware, proper fit cannot be guaranteed. Mounting to rifle-length receiver extension is recommended to ensure optimal fit and funtion.

Exactly what I paid for
Quality of stock is great and was delivered very fast as usual. I could probably have gotten the same somewhere else but buying it here I know I'll be getting the real thing and not a knock off. The product itself looks sturdy yet lightweight, was easy to assemble and both the cheek raiser and the shoulder pad have a lot of travel so I should be able to make it confortable when shooting from any position and place. Certainly a purchase that would last decades.

Another winner.
This is my favorite stock, it’s so adjustable and comfortable. I’ve brought a couple of them and just love them. BROWNELLS is the best, they stock so many of the parts I use for my builds. Love them.
