I'm selling a Trijicon TA44, IE the baby ACOG. It's a fixed 1.5 power prism scope with an illuminated green reticle that's powered by fiberoptics and tritium (so no batters required). It has the Primary Arms exclusive ACSS reticle which has range estimation tools and holdover points. I bought it brand new two years ago and would describe its condition as being like-new. Althought this is a scope, the optic is used more like a red dot or reflex sight. It comes with the original case and a Midwest Industries quick-detach mount (which normally costs $80).
