The Magpul PRS Gen3 is the stock you reach for when you want your precision setup to feel the same shot after shot. Built for AR-15/M16 and AR-10/SR25 platforms, it brings tool-free length of pull and cheek piece adjustment to the table, so you can fine-tune your fit right at the bench or in the field. The machined aluminum knobs turn easily by hand and click into positive locking detents, which means your settings stay put even under heavy recoil. That combination of quick adjustability and a solid lockup is a big part of why this has become such a go-to among long-range and varmint crowd.
One of the best things about this stock is how repeatable it is. The length of pull adjusts across about a 1.4-inch range and the cheek piece raises up to 0.8 inches, letting you line up perfectly behind your optic and lock in a consistent cheek weld. The rubber butt-pad adjusts for both cant and height, so you can tweak your shoulder contact to your exact preference. Get it set once for your build and you'll come back to the same numbers every time.
Magpul didn't cut corners on the guts here. The steel adjustment shafts are finished in Melonite for corrosion and wear resistance, and the aluminum components wear a hard-anodized coat. The reinforced butt-plate is rated to handle recoil up to .50 BMG, which tells you plenty about how overbuilt this thing is for a typical AR platform.
For mounting flexibility, you get rotation-limiting QD sling swivel cups plus a reversible aluminum sling loop at the rear. The M-LOK slots along the bottom open the door for a rear monopod, an extra QD socket, or a section of Picatinny rail. It drops onto a standard rifle-length receiver extension without an A2 spacer and will also fit many mil-spec carbine and A5-length tubes. Made in the USA.
Yes, the PRS Gen3 is designed for both AR-15/M16 and AR-10/SR25 platforms. It's optimized to mount on a standard rifle-length receiver extension without an A2 spacer, and it will also fit many mil-spec carbine and A5-length tubes. Because carbine tube dimensions vary, a rifle-length extension gives you the most reliable fit and function.
The length of pull and cheek piece height are both adjusted by hand using the machined aluminum knobs, so no tools are needed for those. The knobs click into positive locking detents that hold your settings in place under recoil. You will need a hex key for the initial install and for changing the butt-pad cant, but everyday adjustments stay tool-free.
Absolutely. The M-LOK slots along the bottom of the stock are set up for a rear monopod, an extra QD sling socket, or a section of Picatinny rail. On top of that, it comes with rotation-limiting QD sling swivel cups and a reversible aluminum sling loop at the rear for flexible carry options.
It's a solid, substantial stock, which is exactly what you want for a precision or benchrest setup where the extra rear weight helps steady your hold and soak up recoil. If you're building a lightweight patrol or run-and-gun rifle, a collapsible stock may suit you better. For long-range target work and varmint hunting, that heft is a feature, not a drawback.
