Gone Trijicon ACOG TA31F -Factory Refurbished-. It is a 4x scope with a ranging reticle set up for 223. It had a cracked fiber optic tube and the tritium was dim. The lenses were a bit rough. So, I sent it to Trijicon, and they rebuilt the whole thing, including new lenses front and back. They charged me over $200 for the rebuild, but now it's just like new, other than the ugly exterior aesthetics. Price is $750. Aimpoint CompM2 - Factory Refurbished. I sent this one back to Aimpoint this summer for a bad switch. The replaced the switch and circuitry, as well as a bunch of other small stuff. I don't know if they replaced the lenses, but they look good now. It's worn and ugly on the outside, but it's a great sight. You can also have the QRP mount for it, price all together is $350. Aimpoint CompM4 with GG&G AccuCam Mount Like new, just no boxes or anything. $600.SOLD to Andrew. Thanks!!! Click photo to enlarge.
