Armasight night vision monocular quick release picatinny mount adapter - Armasight Night Vision Monocular Quick Release Picatinny Mount Adapter

Well-made product, purchased for use with a Gen2 Sirius on an AR platform...but be aware that this is an "offset" mount - if you plan to mount this on a rifle, it is not designed to align with the bore. It is described as an "observation" mount for the monocular. If you want to use your monocular as a weapon's sight, you will need to purchase the more expensive AIM PRO collimator mount instead (~$450 USD).
