This is a brand new unused Acog Trijicon new 3x30 red .308 BDC reticule model 400022 withTA60 mount. It doesn't need any batteries and works day or night. Reticle lit by fiber optic by day and tritium by night. These are the best optics around for toughness and no maintenance. The TA60 mount mounts to any rail. I have 2 others in green that I love and use on my HK and VEPR, but my eyes don't pick up the color red clear....So I'll sell below cost at $900 or trade for ACOG with green reticle. I also would trade for high end scope 10 power or higher. I'll take or give cash to make it even.
