Status: In-stock / Please Call to Purchase

This Chester County Armory listing is for a used factory original Heckler & Koch HK UMP three position (safe, semi, and full auto) complete lower receiver assembly.

Overall, this item is in excellent condition. Mechanically, there are no concerns, and all parts function appropriately. The polymer lower is completely intact with no cracks, dents, dings, etc.. Cosmetically, the polymer shows only minor handling marks, however, the color on the bullet pictograms is beginning to wear and recede (see photos).
