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've been looking for a cheek riser for my CTR stock for awhile and came across this product. I took the chance and ordered it and let me say, I made the right decision. This product works perfect to align my eyes up with my Vortex red dot scope. I love the fact that it allows me to pull my charging handle back due to the fact that I don't have my stock extended all the way back. Very comfortable and it also gives my stock a great look also. The installation couldnt be any simpler. I also love the fact that they also included a few extra goodie items with my item. Got to love American made products and American companies.

Awesome product and well made. I'm bummed that I had to send it back because it was just a hair too high for my optics setup. I would definitely purchase again for another build if needed.

Easy to install and great quality. This was just the right height to get a proper check weld using the CTR stock for my 16" OBR using the Larue OBR scope mount .

I have been using this product for over a year now, and I am very satisfied with how well it does what it was designed to do. As a riser, is it the perfect height for my personal needs. The ability to access the charging handle and use it to full motion is the real beauty of the design. No need to adjust the stock before charging. I will add that initially it was a bit stiff, and made charging the handle a bit harder than needed, but over time (After a full day at the range), the spring seemed to be much easier to compress, while still maintaining stiffness.

This is a high quality piece that is just the right height to bring my sight line in perfect alignment with my tactical scope. Ingenious way that it "reciprocates" to avoid charging handle interference. (PWS MK114)

I bought this to accommodate a Burris MTAC with the FastFire III mounted on the top scope ring. Without the RISR, I could barely touch my chin on the Magpul MOE stock when using the red dot. With this installed, the purchase is much more solid.

Excellent put it on my ar10 because I like the more compact collapsible stock over the magpul prs. With the Burris PEPR and vortex viper pst 4-16x50 I have perfect eye alignment. Very happy with it.

Superb craftsmanship, easy install. This is my second RISR, and I chose Foliage Green ... the color match to the Magpul fore grip and CTR is spot on. LaRue really hit a home run with this product!
