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.

Own a Magpul CTR for an AR15? High cheek bones? Larue RISR is your solution. Allows me to get the cheek weld right where i need for fast, consistent target acquisition, all while keeping my slide action un fouled. Well made, elegant, tough. 9 out of 10. One point held back for weight. it could be a little lighter if it clipped in like the Magpul design for non AR15's, but i am splitting hairs. Awesome product. Caution FDE is really a very light grey, not like the magpul grey at all.

Purchased this for my son’s 300 HAM’R so his smaller head can get up to the scope better. Fingers crossed he gets his first whitetail in a couple months. This thing is slicker than owl poop! Had to study it for about 7 seconds to realize the stock needed to come off the tube. (Duh). After that it was a simple install with two hands and a Phillips head screwdriver. Screws do not need to be too tight. Fit and finish are excellent. I’ll likely throw down for a couple more for my own tools/toys.

Usual boring Larue quality, since I've never seen Larue product that wasn't a top notch piece of kit. Very intuitive design with the only down side being knowing the bolt is locked open manually since you don't get with the dangling charging handle when the BCG is all the way back. That being said it's very minor adjustment to know your BCG is fully locked back with a 1/3 daggling charging handle. This product is a must for LPVO as well as RDS over 1.73 co-whiteness mounts especially when shooting prone, off axis etc.
