Hk MP5 / 94 Building From Flats

Can be built from the various flats currently available on the market. IGF manufacturing info must be added to the right magwell. A model number and serial number is added to the tob rib. For the most part a customer can have any model number or serial number they would like. The finished firearm will have to be shipped to an FFL dealer for transfer to the customer when the work is finished. Flats are finished only as part of a firearm build.

In most states these can be built as a pistol with the short MP5 barrel, in this form a pistol style endcap must be used in place of the buttstock and no US parts are required.

I can also add a fake suppressor to the 3 lug MP5 barrel to get the barrel length over 16″. In this configuration a buttstock can be used, but they also require 4 US parts in addition to the receiver and fake suppressor which would qualify as US made.
