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!**
