Umarex MP5 22LR Buffer Tube End Cap

Remixed my Umarex MP5 End Cap to accept a standard ar15 buffer tube. This also has design aspects from Hoffman Tactical lowers where a portion of the threads is thinned and a recess has been added for a hose clamp to not only squeeze the threads tight onto the buffer tube, but also allows for pressure to hold all the surrounding layers together resulting in a stronger assembly.
