Nice!!! I'm glad u let me know u were bidding on that thing or I was gonna buy it. If u come to 3 Mils Right Sunday I'll bring you an M1 with the long Tube and all the Accurate Iron goodies so u don't have to do any shotgun loading and you can see what options u want Mike to do to your gun.
Found a place online about 3 weeks ago that actually had 21inch M1 barrels in stock will try to find the address. Of coarse i found it about 4 days after i ordered a 24in barrel for my M1. But I bought a nice used factory 21in camo M1 last week.
