The UMP. Nick's Field Stripping Video Series. Episode 8

Original HK UMP

hk was too cheap to make the ump have captive pins and on the usc they literally said screw it, and so that's what you did cause it was held together with two cheap hex screws. even clones are expensive and you cant find mags anywhere that are affordable. sad cause it really is a great gun, downright therapeutic to shoot

Cool

[@xxxlonewolf49]

Ah yes, the cool, but failed replacement for the MP5 series. Maybe just too early for its own good? Or just the MP5 has an over blown "mythical" rep.

@psp1921tsmg plastic weighs less than metal, so...following the mp5 but made in plastic, yea

[@psp1921tsmg]

@@xxxlonewolf49 it’s not really the weight of the receiver. It’s the giant piece of metal that makes up the bolt. Moving back-and-forth. Actually makes the gun move up and down on the barrel endI guess they needed a heavy bolt and keep cycle rate down , but they should’ve come up with a buffer system and that would’ve made the weapon much more effective.

@psp1921tsmg A heavier receiver would had helped with that as well.

too expensive and not a replacement, was designed for law enforcement at a time when their ammo logistics were less simplified, thus the gun came in various popular calibers and could easily be converted between them. It was definitely too late for it's time though, a product of the 90s that came about a decade too late. In regards to buffering you could probably just stick some cheap o-rings on the back of that recoil rod assembly and experiment with that a bit. definitely doesn't need anything too complicated just needs to be shot with some control, this is not a gun for mag dumping. the receiver itself does have some metal in it but the gun definitely benefits from having more weight to it. The longer barrels that come on the USC guns definitely add something.
