It took me about 10 months, but I finally got the Heat Shield that I wanted for my UZI build through Title Arms. It is worth every penny. I still plan to get the SBR so I can put the original sized UZI barrel on it. But until then I have this.
I wrote an article here about building your own semi automatic UZI. It has the 16inch barrel, because I have yet to SBR it and use the full auto length barrel. It looks strange. So I found the Title Arms page around a year ago. It took me several emails and 10 months before it was finally in stock. I ordered it and it arrived a few days later. It looks like a real silencer. It is not. It is only a heat shield. It gives the UZI a much better look. Price is around $140 plus shipping. They have several other types of heat shields and also metal folding stock at http://www.titleiiarms.com.
