Back in the late 80's- early 90's there was an outfit that would cut down the barrel to 10-12 inches to a M1Super90 to make a very compact entry or urban shotgun (once you got ATF permission of course). Had the opportunity to fire one once and was quite impressed. That company isn't around anymore, but now that I live in a free state would like to convert my M1 to that configuration. Is anyone aware of someone who does this conversion? I live in Nevada.
