The H&K UMP has a positive 13mm internal thread. You will reveal this thread when you remove the orange tip with a heat gun and a pair of pliers. You can get a 13mm positive to 14mm negative adapter to put a standard airsoft thread on the H&K UMP. As the video below points out, the 13mm positive to 14mm negative creates a minor problem of tightening the mock suppressor loosens the adapter. My advice tip... find a 13mm positive to 14mm positive adapter and use positively threaded muzzle devices.
