Umarex HK MP5k Front Cap for Red Dot Sights 3D print model

The Umarex HK MP5k has long been a favorite Co2 Airgun of mine, and I'm having a lot of fun customising mine. However, one of the drawbacks is that you can't fit a red dot sight without the fixed front sight at the muzzle being in the way. This is a simple replacement end cap, that fits on the front of the Airgun instead of the factory fit cap with front sight. The dimensions are exact to allow the fitting to hold in place by friction alone, however there's also a side notch for fitting the threaded grub screw that comes with the Airgun to secure it properly.

Installation is simply a case of removing the grub screw from the existing muzzle, sliding it over the muzzle and replacing this one instead.
