Why does HK refuse to make these?
Heckler & Koch's refusal to produce the UMP for the US market is criticized, forcing enthusiasts to rely on aftermarket conversions like those from TommyBuilt Tactical. The USC, the civilian variant, is undesirable due to its limited capacity and stock. The video highlights the potential of a converted 9mm UMP-style carbine with a 16-inch barrel, contrasting HK's domestic production of other models with their unwillingness to supply the UMP.
