Special Features
Large, hard-coated aspherical lens gives a distortion-free sight picture with a generous viewing window sized for smooth draws and fast target acquisition.
Motion activation with a 10-minute auto-shutoff turns the dot on when the optic moves and powers it down after inactivity to conserve battery life.
ShockShield polymer insert in the housing helps absorb hard daily abuse, protecting the optic when used on carry pistols, shotguns, and carbines.
Fast-Rack front texturing allows confident slide racking off belts, holsters, or other firm surfaces when you need one-handed manipulation.
Top-mounted battery compartment lets you change the CR2032 cell without removing the sight or disturbing your zero.
Deltapoint Pro footprint compatibility means the Defender-ST DFST-MGD3 fits many optics-ready pistols, Glock MOS setups, and common adapter plates, while also mounting easily on Picatinny rails with the included mount.
Ten daylight and two night vision brightness settings make the green dot adaptable for bright outdoor ranges, indoor environments, and low-light work with compatible devices.

The rugged 7075 aluminum body, ShockShield insert, sealed construction, and Deltapoint Pro footprint let you use the same micro green dot across multiple platforms without constant re-zeroing or worry about durability.
