Got an older Trijicon ACOG mount, barely used. $50. Next up is a Matech rear sight, excellent condition. $60. 3rd up is a Set of KAC backup sights. Front was mounted, never shot with. Rear is USMC marked and I opened pkg to take pics so brand new. $250 for the set, not separating. Found another KAC rear sight, $125 for it alone. ZERO tradesies on this stuff.
