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 thing is awesome and totally worth the cost. Using it on a 16" Noveske 5.56 and rang steel at 1000 yards at the FTW shooting school.

Love it. I use 1.93mm height mounts for my LPVOs and have a 2.26 Unity fast riser for my EoTech. This gives me the advantage of getting a solid cheek weld along with the benefits that the higher mounts offer. As for the Riser. Solid. No wobble or slop. But yet no resistance when running the charging handle. Nice and smooth. Will run these on all of my stuff.

Fantastic product. Solid quality. Does exactly what it says it does. Charging handle sliding action is flawless. Causes no issues. Superior cheek weld as well as keeping the stock in the shoulder pocket. Both were issued for me which is why I bought this. Magpul CTR stock and Romeo 5 red dot on Sig M400. Quick and easy install. Well worth the money.

Fits and functions exactly as advertised. The cheek weld is near perfect. The installation was a breeze; the hardest part was removing my stock from the buffer. After that, it was all downhill. The quality appears excellent. The reciprocating spring is positive but gives just the right amount of resistance, does not interfere with charging at all. I am looking forward to some range time (once the temps here in central Iowa get above 10).

Super easy to install, insane LaRue quality, great addition to the Magpul stock. I had this on a LaRue OBR, and I just added it to another non-LaRue rifle, because I could not get a correct cheek weld with the standard Magpul stock.
