Hera Arms USC Conversion Kit

Heckler & Koch's civilian model of the UMP was the USC, but du to import restrictions it was available only with a thumbhole stock. Hera Arms is another Germany company that makes several gun accessories and kits. This one swaps out the thumbhole stock on a standard USC and replaces it with a one-piece pistol grip + stock adapter that can use the ACR or AR-15 style stock. (GRH)
