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.

Works nearly flawlessly. This was for my wife's rifle as her MOE stock had a comb too low for her. I was skeptical, but thought it was only $20, so we ordered it. Installation was a snap, all parts included, no drilling and looks great. The only ding is that when the stock is fully collapsed, you are unable to manually pull the charging handle back far enough to lock the bolt open on an empty magazine. It's extremely close! No matter, as the stock fits her best one notch out anyway. Great product, would buy again if needed!

Was able to install on a magpul fixed carbine stock with minor work. Had to drill holes and slightly file the rails to clear the tube inside the stock. Saved having to buy a ctr! Overall very pleased with the added height and looks!

I have three of these now. Two on CTR stocks and one on an MOE stock. This product works great to get your eye in alignment with AR height scope mounts. It also solves the problem with the interference with the charging handle.

Excellent cheek riser. Easy to install and is solid. Unfortunately it was to to high to allow me to utilize my sights/red dot optic so I had to take it off. Wish it was lower In height so that I could use it on my CTR stock.
