Still a work in progress. I could not find a solid sight mounting option for my Umarex Glock 17 T4E Paintball marker. Honestly there aren't many options for this maker as its design does not alloy for removal of the slide, so I decided to make one.

In this version I haven't added the picatinny rail, but you can screw one in and/or use glue, I used both in the picture. I will update this with the rail once completed. This is designed to slip over the iron sights with enough room to ensure it does not get damaged. It's a snug fit to ensure that it does not slip off when fired. In the next version I intend on adding a screw hole to the back to press against the back plate, but so far it does not move.

The Umarex Glock 17 T4E is a great marker, but it's a closed design, makes it hard to add toys.
