Works on AR15/M4 platforms, as well as any other firearm platforms with a Weaver/ Picatinny/ MIL-STD 1913 rail.
This riser helps with getting low-mounted optics and raising the optic up another ¾ of an inch to a more comfortable cheek rest and shooting height.
The rail has a hollow channel through the length to make it lighter. For some firearms this acts as a see-through sight channel to use the iron sights.
