For sale is my HK USC, 3 10-round HK magazines, and 200 rounds of Federal 45acp ammo.  It's a great gun, certainly a unique design as a result of the 90's assult rifle ban.  Installed on the gun is the HKparts.net picatinny rail kit.  The date code is AA, suggesting 2000 is he year of manufacture.

Asking $1600 for gun, mags, and ammo together as a kit.  Let me know if you have any questions.
