HK USC 45 ACP Carbine 10+1 16" Barrel Black Polymer Stock

The HK USC 45 ACP carbine delivers precision and reliability in a civilian-legal configuration derived from HK's proven UMP submachine gun platform. This semi-automatic carbine combines German engineering with .45 ACP stopping power for competitive shooting and tactical applications.

What Makes This Different

The USC features HK's delayed blowback operating system, eliminating the need for a gas system and reducing maintenance requirements compared to traditional carbines. The cold hammer-forged barrel and precision-machined bolt group deliver consistent accuracy while the polymer construction keeps weight down to 6 pounds. Unlike direct impingement systems, the delayed blowback action runs cleaner and requires less frequent cleaning.

Key Features

• Delayed blowback operating system for reliable cycling with reduced fouling
• Cold hammer-forged 16-inch barrel with 1:16 twist rate optimized for .45 ACP
• Skeletonized black synthetic stock with integrated cheek rest and storage compartment
• Black polymer receiver with Picatinny rail for optics mounting
• 10-round detachable magazine with HK's proven feed geometry
• Ambidextrous safety selector and magazine release for enhanced ergonomics
• Threaded muzzle compatible with .578-28 TPI suppressors and muzzle devices

The USC excels in competitive shooting disciplines where .45 ACP power factor requirements favor larger calibers. The 16-inch barrel maximizes velocity from the .45 ACP cartridge while maintaining carbine maneuverability. Weather-resistant polymer construction and corrosion-resistant steel components ensure reliable function in adverse conditions. The delayed blowback system's inherent accuracy advantage stems from the bolt remaining closed during firing, eliminating movement-induced accuracy degradation.
