How do you price used optics? I have had the Trijicon ACOG with red dot on top for around a year and a half and like it but enjoy shooting my other AR with 2.5-8x36 better. I am thinking about selling the ACOG and one of the AR15's but am not sure whether it will be the SIG516 which the ACOG is on or the Daniel Defense. I will use the other scope on whichever I keep if I do sale.

I believe I paid around 1700 for the ACOG new

AR15.com optic market is a good indicator....Gunbroker advanced search for completed sales on your model another....+ EBay. Lots of data out there to derive a value from- good luck.
