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.

The Larue RISR is amazing. Believe me it's extremely worth it. If you have taller risers for your sights like the Unity FAST mounts, this makes it a lot better to get a proper cheek weld while still getting good vision. Using this in combination with an aimpoint T2 and eotech g45 both with unity mounts. Fantastic combo. Customer service is top notch as always as well. Thanks Larue!

Larue, as usual, was so far ahead of its time with this one. Absolutely love it on my DMR build… will likely be adding to my SBR. Also… UDE… need I say more

Bought this to go on a new build. Like the idea that you don’t have adjust the stock when charging your weapon. Works as advertised. Definitely recommend this.

I only recently discovered the LaRue RISR product, and after purchasing and receiving the first one, I ordered a second RISR a week later. Besides the obvious benefit of the sliding portion of the RISR, the RISR(s) gave me the ability to achieve a comfortable cheek-weld (particularly in the prone position) without having to twist my "seasoned" bones into a painfully contorted position to acquire a proper sight picture on my scoped AR(s). Installation was a very simple and quick process. I'm seeing a third RISR in my future.

Well made. Integrates perfectly with the CTR stock. Super easy to mount. The rise enables me to align my eye with my LPVO very quickly.
