Factory marked with German proof stamps and the DE country code, this USC was made by HK Sidearms GmbH in Germany and imported by Heckler & Koch Inc., Columbus, GA. The BA date code identifies 2010 production, providing clear provenance for buyers who value documented origin and period-correct markings.
The UMP-style conversion equips this rifle with a folding skeleton stock on a left-side hinge and a UMP-style trigger housing/lower featuring the red pictogram selector. Length of pull is set at 15.0 inches, offering a solid shoulder fit consistent with the stock configuration.
Controls and ergonomics mirror the UMP layout, including a left-side charging handle with a notch for locking. The rifle features an ambidextrous safety/selector and a polymer receiver and forend with longitudinal ventilation slots for durability and heat management.
For mounting options, it includes a full-length top Picatinny rail along with right-side and bottom accessory rails on the forend. The 16-inch barrel is fitted with an SD UMP .45 Auto marked cylindrical muzzle shroud, complementing the UMP-style profile.
