The Comp M4 sights incorporate an integral mount that eliminates the need for a separate ring, and can be customized with vertical and forward spacers to fit a variety of weapon systems.
They can also be used by hunters and sport shooters that need night vision compatibility.
The Comp M4 series of sights are available in two versions:
The CompM4 offers a high battery compartment, while the CompM4-S offers a low battery compartment.
In all other aspects, the Aimpoint CompM4 and Aimpoint CompM4-S are identical.
