MAGPUL PRS GEN3 Precision Adjustable Stock

(14 reviews) Write a Review


The PRS GEN3 is a field precision stock for AR15/M16 and AR10/SR25 platforms, featuring tool-less 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. Offering a nearly universal fit, it is optimized for rifle-length receiver extensions but will also mount to many mil-spec carbine and A5-length tubes*. Includes a cant/height-adjustable rubber butt-pad and rotation-limiting QD sling swivel cups as well as M-LOK® slots on the bottom for rear monopod mounting.






  • 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)*
  • Enhanced strength butt-plate withstands severe impact and recoil up to .50 BMG
  • Rubber butt-pad provides positive shoulder 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-8625F, Type III, Class 2 hard anodizing
  • Bottom M-LOK slots provide additional sling mounting possibilities or for attaching 1913 Picatinny rails for use with a monopod
  • Sling Mounts
    • Front/Rear - rotation-limited QD sling swivel mounts (swivels not included)
    • Rear - 1.25" aluminum sling loop (left-right reversible)
  • Made in the USA


*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 a rifle-length receiver extension is recommended to ensure optimal fit and function.

    When I got my Ruger Precision Rifle, I was totally turned off by the factory butt stock and found the simplicity MAGPULs stock to be much better. I did however replace the factory buffer tube with a rifle length one.

  • Does work with magnum calibers

    I have this on my Ruger Precision Rifle chambered in 300 PRC. Takes about 10 minutes to remove the old stock and put the new one on. You do not need a different buffer tube

  • Great stock

    I have a RPR , in my opinion this stock is much better than the factory RPR stock , it adds some weight , no cams to mess with , just rotate adjustment knows and done !

  • Don't need rifle length buffer tube for RPR

    Magpul has added a carbine length buffer tube compatibility to this model. That saved a lot of time, two screws to secure this stock and it's absolutely solid. Great stock, would recommend!
