Check to see if the o-ring is present and undamaged. Also I have seen the brass threads damaged for the protective caps. I have seen used ACOGs where the adjusters were very badly damaged from people using the wrong tools to adjust them. Check the windage and elevation adjusters for damage. Generally I would recommend against buying ACOGs with damaged lenses unless you are getting a very good deal.ģ.

While I could not get them to show up on camera, this particular ACOG has some nasty scratches and damage to the ocular lens. ACOGs can get run hard, so clean the lenses and check them for damage and scratches. For example this optic was made in 2007 and was sold to Optics Planet.Ģ. Also you can find out how old an optic is. You do not want to spend your money on stolen property. I highly recommend calling Trijicon and finding out if the optic you are looking to buy is stolen government property. Often you can also find the serial number on the left side of the ACOG. Serial numbers are always on the top of the ACOG. When you are looking to buy a used ACOG, this is what I recommend you do:ġ.

Since 2006 I have owned over a dozen ACOGs, buying them cheap, and later selling them for a profit. I am a big fan of the Trijicon ACOG ever since I used one in Iraq.
