... You brought up something I just started thinking about --> with motor selection in general, and reloadable motor systems in particular, how do you put in a motor retainer when the various lengths...vary?
The aft closure on reload hardware is a larger diameter than the MMT, so it is a stop. A motor retention system for MPR/HPR typically has a permanent male threaded collar bonded to the aft end of the MMT that the aft closure fits into. A female threaded ring is screwed onto the permanent collar and secures the aft closure on the motor. Works for single use as well (if it has an large motor ring at the base).
