NcStar FlipDot M2 3 MOA Reflex Sight for Glock MOS

The VISM FlipDot M2 is a folding reflex sight. The lens lies flat when it is not in use and turns the optic off; one push of the button flips it up and switches it on. The 3 MOA red dot adjusts for windage and elevation, and a backup rear sight is built into the body with a front post on the bottom of the lens frame, usable through the glass when the lens is up.

Mounting is the main reason people pick it. It goes directly onto Glock MOS slides with the included MOS plate and screws, and a 2mm spacer covers most RMR cut slides. A Glock rear sight dovetail base and a Picatinny/Weaver mount are in the box as well, so it can also go on a Glock slide without an optic cut or on a rail. It weighs about 1 oz and runs on a CR2032.
