Another riser: OMM by IRREGULAR DEFENSE

OMM – Optic Mount Modular – is the rail from IRREGULAR DEFENSE. The base can be either a mount suitable for Aimpoints, or a classic RIS rail, such as for EOTech.

Depending on the need, a further RIS rail can be mounted at the front and/or rear to make room for a magnifier or laser box. The base mount price is $215 for the RIS variant and $265 for the AIMPOINT version. In addition, there is an additional $90 for a short RIS rail extension or $111 for the long one.
