The Holosun Technologies SCS MOS is a black dot sight designed for handguns with a Glock MOS system. It has a multicoated lens and a green reticle color with multiple reticle patterns, including a 2 MOA dot. The sight is made of titanium and powered by a lithium-ion battery with unlimited battery life. It is parallax-free and has unlimited eye relief.

This was briefly mounted to a Glock 26 MOS than I unfortunately had to sell. Never shot the firearm optic was mounted and never used/sighted in. Has tiny bit of blue thread locker residue as pictured in screw hole. Other than that in brand new condition ready to use battery charged.
