Trijicon MRO and G43 Repro. Has killflash, two mounts (high and low), batteries and lens covers. Mounted on my Mk18 for about 30 minutes and then put back in the box. Literally brand new condition. Unlike other sellers on here, this is not dropped shipped to you, I actually have this ready to be shipped out to you within 24 hours (provided it's not the weekend).
