The Heckler & Koch UMP (Universale Maschinenpistole, German for "Universal Machine Pistol") is a submachine gun developed and manufactured by Heckler & Koch. Heckler & Koch developed the UMP as a lighter and cheaper successor to the MP5, though both remain in production. [4]

The HK UMP is freely configurable with regard to its features. The optional equipment portfolio ranges from the classic skeleton buttstock to the use of tactical helmet buttstock variants. The UMP is available as a semi-automatic or fully automatic submachine gun.

MGW offers replacement triggers, sights, magazines, firing pins, screws, springs and other small parts for these rifles. Outfit your Heckler & Koch UMP or USC with quality OEM and aftermarket parts and components to ensure outstanding performance with every shot.

Aug 5, 2022 · I'm working on converting a usp40 to 10 but I'm having a hard time finding an aftermarket barrel that can be reamed for 10. Already have the mags cut and everything. A roller locked 10mm would be amazing.
