Nerf Hammershot Front mod

This is am Front-End-Mod for the Hammershot. NOT FOR STANDART CYLINDER.Made for : https://www.thingiverse.com/thing:1274005 It i based on a model from deusnefum. https://www.thingiverse.com/thing:3263973 I improved it so it has more tolerance for the darts in the front.I also added some chamfers, a spacer and on one Version the standard nerf barrel mount.I also improved some tolarances.There is a little groove to insert a rubber O-Ring into. So even barrels without endstop fit and sit snuggly.
