HK USC to UMP40

[JumpmanUSC]

One of my very first SBR projects. SBRd the original gun then got a UMP40 bolt and barrel and here it is. 9mm conversion is in the very near future .

Why would you waste your money swapping to an "inferior" caliber. Everyone knows .40<.45!

Sweeeeet SMG!!

Another great looking gun. Did you mill your bolt yourself or did you send it to Ed? Also where did you put your SBR info? I was planning on putting mine on the barrel so it can be seen through the lower vent hole.

Corey,
Jeff at Tactical Excellence did the bolt for me (just before he called a sabbatical from the conversions), Jayson from IGF milled the magwell and vents and also the engraving. My info is engraved on the left side under the HK USC markings. Should have done it on the barrel like you are thinking but oh well.
