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.

This RISR fit perfect on my ar15 commercial ctr.easy to install. It takes just a few minutes. I would recommend and definitely buy again on my next build. RISR comes with all hardware and all you need is a screwdriver.

Super fast shipping with lots of swag in the box. Only took a few minutes to install, the tube of thread lock was another nice touch. My wife has bad arthritis in her neck and shoulders so the extra height made getting a good cheek weld much easier for her. The spring is a little stiff for her when charging the rifle but it did seem to ease up as the day at the range progressed. I found no problem racking the bolt myself, the Raptor CH worked well with the RISR for me. Only downside is my favorite MechArmor ambi CH doesn't work well with it.

One of my duties and responsibilities at work is to design injection molded parts industrial use. The injection parts from LaRue would be considered of high grade. No sink marks, gates, visible flow or knit lines. No externally visible ejection marks. The design is "elegant" basic but it fulfills the design intent. My only wish would be to make its height adjustable. Rifle is a POF. without the RISR my scope/ring combination felt low. with the RISR it may be a tad too much, will find out at the range.

Excellent riser. Very nice quality and comfortable. The reciprocating feature works perfectly with my Raptor. Larue is that type of company that always goes above and beyond for their customers, if you've ordered before you know exactly what I mean.
