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.

Awesome RISR! I purchased this to install on my wife's rifle and she now gets a better cheek weld. Would definitely recommend this great product, very easy and quick to install, durable and very affordable. Thanks LaRue.

Nice addition to my CTR stock, I did notice it will be too high for my scoped AR (normal 1.5" hight scope mount with NF scope) I really needed to push my face down, but I know it'll be a great addition for my AR with either the red dot or Eotech. It's quality and I look forward to using it

Installed the RISR on my wife's rifle and also on each of my daughters rifles. All using the 6.5 grendel platform for deer. Works great for their smaller frames! And since they have a shorter LOP there was no other product that I have found that works as well as the RISR. Can say that I however cannot use their rifles now. With standard height optic mounts I can't get a sight picture. The standard AR stock has the perfect cheek weld for me.

Installed in 5 minutes. I am now able to get a good cheek weld and have my eye aligned with my SWFA scope. The rifle comes up naturally and I don't have to move my head around to get a good sight picture. Will buy more as I have 3 more rifles with high rings on them.

How is this not sold more? This is an absolute must have for the CTR stock.
