Wow - but I do not see a market for them -
There are MILLIONS out there in the hands of OLD Crumudgeons that have history with them - once they all start dying they will flood the market and can be had for a song.
I always said M1's were not a good investment for that reason - too many around.
I cannot see how they are going to make money - when you can go the CMP route.
The only way to make money in M1's is sell them NOW.
Yeah, it's crazy. I really think it's the 18.5 barrel that first time owners are looking for rather than any specific brand/model. If it's USA made, it's sells at a big premium. The Turks and the dealers have been able to capitalize on this by flooding the market with Turkish shotguns for home defense around the $300 level. Not a bad deal if you got to have one in today's environment. If it saves your bacon, it's really priceless.
Here's another recent Mav 88 auction: $565 + shipping + FFL transfer fee (well over $600 net)
