For speed and precision, nothing performs like a red dot, and Athlon's Midas TSR1-M delivers everything you could want: premium fully multi-coated optics for brightness, extended 50,000-hour battery life, and a sharp 3 MOA reticle that puts you on target in a flash. The one-piece, aircraft-grade aluminum chassis is 100% waterproof, fogproof, shockproof, and tough enough for regular duty operation. Best of all, the Midas features motion activation technology that turns the unit on when it senses movement-so you don't have to fumble with buttons or switches in high-stress scenarios.
