Magpul PRS Gen 3 Stock



Durable, sturdy and dependable, the Magpul PRS Gen 3 Precision Adjustable AR-15 Stock is the perfect butt stock for precision rifles. Its weight of 27.8 ounces adds bulk to your gun while giving you the support necessary to hit long-range targets with unprecedented accuracy.

Compared to the standard A1 / A2 stock, this adjustable butt stock adds more flexibility to your rifle. It allows you to contract the length of pull an extra ¼ inch shorter or extend it ¾ inch longer. This functionality lets you customize your rifle to each specific environment you encounter.

Made in the U.S.A., the Magpul PRS Gen 3 Precision Adjustable Stock features an adjustable butt plate and cheek rest, which can be fine-tuned to your preferences using two knobs. The knobs are easy to manipulate, yet they still hold their position in rough handling and recoil. The durable aluminum butt plate is built to withstand the most formidable recoil, even that of the .50 BMG, while the textured rubber butt pad prevents slippage when firing. The M-LOK slots on the bottom can accommodate a monopod for greater accuracy. Law enforcement, military, or competitive shooters will all find that Magpul's PRS Stock Gen 3 takes their accuracy to the next level!**

    Product as describe and the fastest company I have dealt with in processing orders. I have made two orders and both have shipped same day if not within a couple hours of placing the order!

    I found it was easy to install and nice for the set up I have for a twenty year old rifle(it needed an upgrade)
    The adjustment wheels are a bit stiff when new and Im sure it will be better in time. I shopped for price and these guys had the lowest that I could find. Nice set up and it looks good to : )

  • Expected as the description

  • Excellent quality

    Simply the most comfortable, most adjustable, and solid stock available for an AR platform. Makes it really easy to have consistent accurate shot placement.

    I selected the MAGPUL PRS GEN 3 PRECISION ADJUSTABLE STOCK for the following reasons:
    No. 1. The new stock replaced a MAGPUL, ACS-L™ Carbine Stock of the same color. Installed on a Sig Sauer SIG716 Patrol Rifle.
    No. 2. The MAGPUL PRS GEN 3 PRECISION ADJUSTABLE STOCK offers length of pull and cheek piece height adjustment that the ACS-L stock didn't have. This is a must have for me on the Sig 716.
    No. 3. MAGPUL has a rock solid reputation for quality. I have had nothing but good experiences with their products.
    No. 4. The MAGPUL PRS GEN 3 PRECISION ADJUSTABLE STOCK is a direct fit to my rifle.
    Directions are clear and Installation was easy with only one tool required to complete the job.

    Simple to install. Took 5 minutes or less to take the factory stock off my M&P 15 and put this one on. Added 1 1/2 inch of much needed length, nice recoil pad, (not that it was needed) & stability to the slightly wobbly factory stock ... My accuracy improved a bit ... Made my M&P more fun to shoot and looks really cool (a definite plus)

  • Would recommend

    Very nice and fits well. Glad you can use on carbine buffer tubes or rifle tubes.

    Wing Tactical rocks!
    Their price is unbeatable!
    The stock was easy to install, and it performed well beyond expectations. I Installed it on a DPMS clone, and now it is a more precise tool. Virtually no recoil. Well, the rifle also has an adjustable gas block, but the Magpul stock is what makes the difference.
    I will definitely come back and buy more products from my brothers and sisters at Wing Tactical.
    No doubt!
