Good call! Very few know the StG-43 and how Mr. Kalashnikov copied it to build the AK-47. Unfortunately, I missed the early days of the "Investment Firearm" era and those toys belong to a good friend. I may eventually convert one of my HK trigger packs to select fire, but HK auto sears recently skyrocketed to over $10K. All the government restrictions and bans actually did was create a very lucrative and profitable weapons market.

One friend is building a single-shot 20mm based on a Vulcan barrel (as pictured earlier) and a custom receiver. Think I'll wait till it's broken in before popping a few rounds through it though. LOL!
