HK UMP .40 S & W Calibre Conversion Kit | USC compatible w/ gunsmithing

I have here an original HK .40 S & W calibre kit! Comes with the barrel, complete bolt carrier, one 5/30 rare LE mag, and a barrel pin. Excellent condition.

I am asking $2250 + shipping.

This kit can fit the USC with a gunsmiths help. Part of the side needs to be milled. Ask me for more details.
