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.

I bought this LaRue Tactical RISR for the MOE stock on my Seekins Precision NOX Billet 16 rifle to cure a sight alignment issue due to lack of adequate check weld. The RISR functions flawlessly, well throughout engineering design, and beautifully finished. A+ LaRue1

This fits absolutely perfectly on MagPul CTR, quality is top notch. Seriously, after installing it and trying it out in a field I can not imagine using CTR stock without it. If you have a CTR stock - get this riser, if you don't then get CTR and put this riser on it and you'll have the best stock in the world :). And it really helps with quicker eye sight alignment with optics if you have red dot or a scope. Plus its ingenious reciprocating design solves this too well know problem with cheek risers and AR platform clearance for charging handle - no need to move stock back to lower the riser to charge :). End to end, I'm very happy with this product and recommend to everyone. Vlad S., San Jose, CA.

Another great product from Larue...fit is perfect and couldn’t be easier to install. Great cheek weld. Mounted on a black CTR and looks 100% Factory. I was lucky enough to grab this piece for a sale price that felt like I was stealing...100% recommend.

I installed a couple for a friend on two builds. Wasn’t sure about it. Then I picked one up on sale. Took some getting use to with getting a sight picture but it was worth it. Really completed the build. Will definitely buy again.

As far as aesthetics it looks awesome and very functional. I mounted mine on a blackout build and it lines up perfect with my eotech and Troy iron sights. Thanks LaRue....
