The Truglo Tru-Tec Micro Sub-Compact Open Red Dot Sight (brand part no. TG8100BM) brings the favorite features of Truglo’s Tru-Tec line into an ultra-lightweight, versatile package weighing just over an ounce. Whether riding the slide of an optic-ready handgun or mounted on a rifle or shotgun, the Micro uses a 3 MOA red dot reticle for fast target acquisition through a 23mm x 17mm multicoated objective lens. Digital push-button brightness control across 10 settings and an idle auto-off system help balance visibility with battery life. CNC-machined from aircraft-grade aluminum, it’s water- and shock-resistant with locking windage and elevation adjustments, a common lug and bolt pattern for broad compatibility, and a TG8200B mount compatible with Trijicon RMR mounting systems. A Picatinny rail mount, ABS hardshell cover, and CR2032 battery are included.
