Unfired Polymer80 Glock 19 slide, RMR cut with cover plate. 17-4 steel, complete with Polymer80 upper parts, and suppressor height Night Fision sights (tritium front, black out rear). Guide rod is included but no barrel. The slide came with the RMR cover plate installed with 1/16" allen head screws. And I managed to round one screw when taking it off. I don't recommend reuse them. The RMR cut is compatible with Holosun 509T with a RMR adapter plate. $260 shipped without Holosun. $450 shipped with Holosun 407C x2. The Holosun is like new with everything in the factory box.
