Thanks Spank for the clarification

I bought all of my parts from Mr. Super X they called him at the time Bob Baumgart who passed probally more than 10 years ago. We would send triggers etc down for him to work on in the days I could send it in the mail and he would send it back done with zero paperwork and no laws broken. I bought enough to still have a stash but my buffers are the second year design plastic ones which are normally good for 50,000 or so rounds
I have never flipped a tube to save a few pennies vs buying a new one in chrome or stainless
Still had seven or eight of these when I joined the site just a couple of years back but sold some here etc and kept four including a miss flyway, two skeet and a trap.
Many say winchester produced two proto type 20ga and I remember seeing pics of one on display. Others say they were conversions that Ray something or other a gunsmith in the US was doing
Would have been nice if they did. I remember when I bought my 10ga gold when it first came out in the early 90;s and took it apart
Man oh man someone sure used the old superx1 designs as a basis for this gun
Cheers
