This is an original WWII German MG 42 parts set, cut from a working gun with live 8mm barrel. Somewhere in the firearm's history it was re-armored in Yugoslavia and they replaced some of the components. We have looked over the kit and found the original Waffenamt stamps mixed in with re-armor stamps. See Photos. This firearm was cut under a special variance from the ATF and you can see that the font section is not cut. Also the rear cut was made behind the lockup so that when the firearm is re-manufactured as a semi those two critical datum points are in the original specified location. Rear receiver parts and semi parts are available from BRP. This kit comes with some accessories -mg42/34/53 linker -Mg42/53/G3 AA mount -Mg42/53/G3 Lafette mount -Mg42/53/G3 Field Cleaning Kit
