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.

It’s great !! The only thing u could do to make it better, is make it different heights I would like it 1/2 inch higher.

We've purchased multiples of this RISR in past years, and have just ordered multiples of them again. We have found that with any scope mount other than low rings, this part gets the shooter back onto the rifle with an excellent cheek weld. This especially true of the red dot, which seems to sit even higher. In addition to correcting "shooter-sight-alignment" problems; its nice that the top of the RISR actually will move with the charging handle, if the stock is collapsed. In an emergency racking situation, that could be the difference. Four screws on each side secured with supplied thread locker are attached to aluminum bar stock that runs in a channel on either inside. It's a solid mount, and since the actual stock is sandwiched between the riser and the bar stock, it's not going to get marred up. In summation, one could say: This little piece is designed a "overkill" at its finest - but then you'd have to add what does this outfit make that isn't overkill? LOL - Chuck - San Antonio

All things LaRue, finest. Another bad ass toy that will tickle you pink. Especially with it newly discounted. This is my 4th one and it is the best cheek riser ever for the AR platform. No matter if your stock is all the way forward or to the backside the charging handle easily charges a round into the chamber thanks to a spring that jacks the cheek riser to the rear of the stock. Pretty cool stuff for $19.95. Installation is a breeze. Can't go wrong, Bothers.

This is the second rifle I’ve put the RISR on and be putting one on every AR I guild subsequently. Great product, that performs flawlessly, and the FDE, is a great accent along with the Magpul FDE mags on my 300BO.
