Well Gentleman, I made the stock myself by altering the factory thumbhole stock by cutting the butt off at the rear of the pistol grip using a mitre saw. That is where the welfare comment came from as opposed to the Tactical Excellence conversion which uses a genuine UMP lower receiver.
I then purchased a B&T (swiss built) MP5 stock, which uses a UMP profile stock. I then cut off the piece which fits onto the rear of the MP5 receiver, and grafted the two together. I used the RIT fabric dye method to colour the plastic.
The barrel is an import from the US. I purchased the Flash hider from the US as well.
