I have for sale a Trijicon MS03 red dot sight w/Tandem mount for a 4x ACOG. The sight has seen some use, but functions fine. The ACOG mount has ears that protect the sight so it never received any damage as a result of its use. I'm trying to get $250 for the whole setup, and I'm not really looking to seperate them. A new MS03 costs around $400 and a new ACOG mount is around $100. I initially bought this to put on a Glock but decided I liked my night-sights too much. A mount for a Glock or pretty much anything else will run you about $50 off the internet. PM/email me with questions. BTW: I'm actually located in Fort Rucker, AL, I just noticed a similar post on this forum and noticed several people interested.
