The H&K USC 45 is a pistol caliber carbine that closely resembles the iconic UMP submachine gun. The H&K UMP submachine gun was created based on the MP5 weapon system except is was designed around the larger .45 ACP cartridge. The Heckler and Koch USC utilizes the same reliable blowback operating system as the UMP and features the same polymer frame construction. Where the Heckler & Koch USC 45 differs from its military counterpart is the integrated skeletonized stock and of course—only has two selector positions. Additionally, it features a 16.5” cold hammer forged barrel.
