HK UMP/USC CONVERSION
SERVICES AND PARTS
The USC to UMP conversion is very popular with HK owners and enthusiasts. The basic USC is not as versatile and not nearly as ergonomic. What you gain by doing the UMP conversion is not only looks and authenticity, it’s also a better feeling and better handling gun. The feel of the grip itself is much better and the folding stock option is a big improvement over the fixed USC stock. If you are in a state that does not allow the folding stock, it is still worth it just for the better ergonomics of the UMP grip. These ergonomics greatly improve the shoot-ability and feel of the USC.

- No pinholes in final finish
- DuraCoat Firearms Finish w/ slight texturing, NO SPRAY PAINT!
- Masked engravings to prevent texturing grit from obstructing markings
- No rough edges or internal blemishing, bolt will slide perfectly, just like factory
- No cracking, splitting or other weld failures, guaranteed ( 100% track record to date )
- No rushed work/assembly line procedures or “unskilled help”
- Hours of special attention to detail will be spent on YOUR project…
