LaRue RISR™ – Reciprocating Inline Stock Riser
Achieve the perfect cheek weld without sacrificing charging handle access.
The LaRue Tactical RISR™ (Reciprocating Inline Stock Riser) is designed for shooters running optics or elevated rail systems who need additional cheek support for consistent sight alignment. Unlike traditional fixed cheek risers that interfere with charging handle travel, the RISR™ features a spring-loaded reciprocating design that moves rearward with the charging handle and automatically returns forward when released.
This innovative system allows you to maintain a comfortable cheek position while still fully operating your rifle—even with the stock collapsed.
Constructed from durable glass-reinforced polymer, the RISR™ is lightweight, rugged, and built to withstand demanding use in the field. Installation is simple and requires only a few minutes using the included hardware.
Designed specifically to fit Magpul CTR® stocks without modification, the RISR™ provides a reliable solution for shooters seeking improved ergonomics and consistent shooting performance.

Very well designed and manufactured product. It does not wobble or retract too easily. With the RISR mounted to the Magpul CTR stock, my line of sight is right where I need it for my Nikon P223 3-9 scope / Burris AR PEPR mount set up. I also added the extended stock rubber pad to move the stock further away from my head. This allowed more of my cheek to sit on the RISR. The kit comes with all the hardware and also a small tube of blue lock tight. All you need is a Phillips head screwdriver and in less than 10 minutes you're in business If I could improve it, I would maybe want the ability to have it be further forward on the stock and have the ability to adjust higher via add-on blocks or threaded dial. That said, it's still 5 armadillos for me. Note: This will not fit the standard AR collapsible stock at least not without significant drilling and channeling. Just buy the CTR stock and you're good to go. Great product LaRue.

It works remarkably well. The reduction in price makes the RISR a steal.

The RISR reduces 1/2' of a low sight picture problem. I am overjoyed at not having to use padding that falls every time the charging handle is activated.

The "risr" runs great. When I got it all setup it did catch a few times while I was running it. I put a couple drops of frog lube and it runs flawlessly!

Fantastic upgrade!!!! Installed this on my POF P415. Installation took maybe 2 minutes. Simple Simple. Sturdy construction. As far as application goes, I installed this to use with my Vortex Strike Eagle 1-6x24 in Burris PEPR mount. Cheek weld problem solved!!! Fantastic!

Unbelievable quality! Customer service is second to no other! When I hear that something is made in America I think of these guys. They are the standard of quality and customer service that you don't see outside the country. There are copycats out there in China especially that unethical are claiming that they sell genuine LaRue products. Let me tell you, not only is this wrong, but it should be illegal and it should be penalized by our government. These lower quality products are not even close quality-wise. If I ever need anything else, I know that I can count on LaRue. They are a top notch company!! Very impressive!

Like all the other reviews say, it just works. It's also how Larue sends you all kinds of free stuff with each purchase.
