It's a fact that some AR's need a cheek riser to get proper cheekweld for raised scopes or rifles with raised rails.

The LaRue RISR solves these problems.

Made out of glass-reinforced polymer, the RISR is spring-loaded and travels rearward as the charging handle moves to the rear, then snaps forward when the charging handle is released. Designed to fit the Magpul CTR butt stock without modification and installs in a few minutes using a Phillips-head screwdriver.
