Derived from the HK UMP, the USC is a civilian utility carbine that uses the classic hard-hitting .45 ACP cartridge. Matched with the simple and ultra-reliable blowback operating system, the HK USC is a radical departure from traditional firearms designs. Extensive use of the same durable, reinforced polymers used on HK’s line of military and police arms ensures light weight and durability. And the highest grade of weapons steel is used where it matters—in the cold hammer forged target barrel and the solidly-constructed bolt mechanism. User ergonomics are not sacrificed. The skeletonized buttstock is topped with a comfortable rubber cheek rest and recoil pad. The web of the pistol grip is open for a comfortable shooting handhold. Hard points located on the top and front of the receiver make attachment of optional Picatinny rails easy, allowing almost any kind of sighting system or accessory to be mounted.
