I'll be honest, I was a little sketched out by this website and the prices, especially! But this was one of two links referenced in blog explaining what I needed to purchase in order to convert my Walther P22 to being suppressor-ready. I was really worried that I'd given my credit card to a scammer and they were going to buy all sorts of goodies with it for themselves. But sure enough, after a few days the package shipped, and although the tracking information was awful, it arrived within 4 days of ordering it! Fits perfectly and I can't wait to test out the suppressor on the Walther! And all for 1/3 the price of the next best competitor! Easy decision.
