I wanted a TKO kit with a squared off muzzle. I also wanted it with a crisp target sight, so I made one. Additional Parts needed: Three 114 O-rings (5/8" ID, 13/16" OD, 3/32" wall) One M3x20mm bolt One M2x20mm nut 17/32" OD brass tubing For 100ish FPS, 45cm of brass works well. With 45cm, the brass sticks out slightly, but not too much. Files for a plastic cap are provided. The shroud needs to be printed with the collet end facing up, and the front of the sight as the bottom surface. The inline clip needs a raft to print properly, standing up with the muzzle end down and O-ring slots on top. The rear sight requires the last 3 rail bits be clipped off, and is a friction fit. Some filing and sanding may be needed to get the inline clip to fit properly into the shroud.
