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.

This is my first Larue purchase and I am very pleased. The R.I.S.R does fit perfectly and I now have the cheek weld I need for the red dot I use. Haven't taken it out to the range yet, but it seems very solid and secure. The extra screw is very nice, they must know me and how many times I'm looking for the one screw that I dropped. The other items in the package are a really nice touch and surprise. I still have another lower to build so I will be getting another of these in the future.

This seems to be a very well thought out genius idea type of accessory. So far on both an AR10 and an AR15 it works very well. Provides a much better cheek weld and gets my eyeball to the right place behind the scope. On the negative side, I would be hesitant to carry this in any life or death type role. There is a very modest increase to the amount of effort required to retract the bolt due top this and there is also a very very slim chance of the mechanism jamming under dirty conditions which could be embarrassing at best.

Fantastic addition to my Magpul stocks... It works on both the CTR and MOE models I have... I've bought three so far, and will be buying a few more. If you want a good, repeatable cheek weld on your stock and have just about any kind of optic... This is a must. I especially like that I can keep the stock collapsed, and rack the action. OUTSTANDING product!!! Thank you. And thank you for the DilloDust I smoke brisket with your Dillo Dust and get compliments every time.

If you are reading this trying to decide if this LaRue product is the best quality you can find, please understand that every thing LaRue sells is second to none. What I can also say is that even though I am not the biggest spending customer ( yet ) LaRue still treats me like their best customer, and that has earned my loyalty.
