Basically just the title. Looks great on any “9mm” build and will also work on glocks. It is “one of a kind” as far as i know, since the mount had to be modified to fit the rmr properly. It works great with a dye mask, im simply selling it because I prefer t1 style optics I dont know what on earth you would trade for this but it wont be anything im interested in unless it is a tlr or repro. Shipping will likely be split
