in the late '70's, early 80's. The fact is that there's hundreds of thousands of guys who are interested as hell in home-built, non-registered cans. I had no trouble whatsover selling all of the cans that I could make, provided I had a .22 pistol attached and as part of the deal, and I couldnt even get around much in S CAl, while on the run and dealing. I got $300 apc, even on pos Jennings .22 pistols. Today, that would be $700, due to inflation. Made and mounted 40 of them, on 40 pistols in 4 days. 6k a day, dudes.
