A cheek riser that moves back with the charging handle when using collapsible stocks.

It’s a fact that some AR’s need a cheek riser to get proper cheekweld for raised scopes or rifles with raised rails. It’s another fact that standard AR charging handles require a lot of travel, making it impossible to charge a rifle without moving a collapsible stock all the way to the rear. The LaRue RISR solves these problems.


Made in Texas, USA, out of glass-reinforced polymer, the RISR is spring-loaded, and travels to the rear as the charging handle is moved to the rear. When the charging handle is released, the RISR snaps forward. Designed to fit the excellent Magpul CTR butt stock without modification, the RISR only takes a few minutes to install with a phillips-head screwdriver.
