Derived from HK’s UMP platform, the USC is a German-made semi-automatic carbine chambered in .45 ACP with a stated 10+1 capacity. Its simple, robust blowback action is paired with a left-side charging handle and an ambidextrous 2-position safety for straightforward operation.
The 16-inch cold hammer forged, unthreaded barrel reflects HK’s manufacturing approach for durability and consistency. Open sights consist of a protected front post and a rear sight base integral to the receiver. The receiver also provides three factory bosses for mounting an optional top rail if desired.
Construction centers on a steel-reinforced polymer receiver and frame with a uniform light gray finish. The fixed, skeletonized thumbhole stock includes integral sling points and delivers a 14.25-inch length of pull. Overall length is approximately 35.4 inches, and weight is about 5.9 pounds, giving the carbine a balanced, manageable feel.
Markings include the Ulm proof antler, Eagle over N, and an AA date code confirming 2000 Ulm proof. Rollmarks read "Heckler & Koch GmbH Made in Germany" and "Heckler & Koch Inc. Sterling VA," underscoring its German manufacture and U.S. import lineage.
