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.

Great product. Works well on my CTR for great head alignment behind a SPR-15 mount and glass. Looks great as well. Installation is quick and easy. Highly recommend for a RECCE/SPR build. John C. Rockwall TX

Comfortable fit on the Cheek and makes for a better stock weld. It will add a slight amount of resistance when pulling the charging handle to the rear but not noticeable when racking it hard. I know this is just my facial construction, but it’s a tight fit with one of my Larue mounts. Probably just my long cheek bone.

This item did solve a problem for me and this combo with the CTR/Limbsaver, will be on any rifle I put a red dot piggyback on a scope (think RMR/ACOG but Deltapoint/MK5HD). Instead of having my chin floating in space while looking thru the dot I can now get my chin comfortably on the stock making target transition normal again. I would recommend picking up some $3 foam stickers from XLR to go on the cheek rest. More comfortable than hard plastic.

This is definitely the best option for a cheek riser for the moe/ctr magpul stocks while still being able to use the charging handle.

Excellent product! After doing hours of research and all the same where you must extend your stock to charge your bolt because the other cheek risers would be in the way & THEN put your stock at the appropriate distance for your eye relief! Who in a dire situation has time for that when seconds count for your life!!! Proper height for scopes! Spring tension is not flimsy! super easy to install! Had stock off and installed RISR & put back together probably :30 min!!! If your in the market for a cheek riser get you a Magpul MOE or CTR stock & this RISR it will not disappoint! This is not cheaply made! it is worth every penny!

excellent product! easy to install! perfect eye level with my scope! spring tension when pulled on charging handle is firm doesn't feel cheap at all! trying to find a compatible cheek riser was a pain and after a long while of searching and reading that they ALL interfered with charging of the bolt and you would have to 1st fully extend your stock to charge & then put your stock in the proper position for your eye relief distance, Who has time for that in a serious situation when seconds count for your life, especially in these no funding of Police cities & states!!! QUIT LOOKING & PULL THE TRIGGER ON THIS YOU WILL NOT BE DISAPPOINTED!!!

I bought one to see if I liked it. Ordered three more the same day I received and installed the one. I like it for even the lowest of the Larue mounts. The cheek weld just feels so perfect. The card that comes with the stock would have you believe that the screws that hold the piece to the stock are 6/32 x 5/16. They are actually #6-32 x 5/16".
