Yeah, good luck with that. I'll believe it when I see it.
AutoMags are gashogs, you need the highest input possible to make them run correctly.
To explain why would take a longer post.
The best thing about an AutoMag is the ease of operation. There are only 5 moving parts and it can be completely rebuilt with no tools.
Beyond that, the AutoMag was one of the top two tournament guns for more than 10 years before electros came out.
Even today (in the age of eletronics) an AutoMag is still one of the top-level mechanicals on the market.
This would explain why you don't see them or the major parts for them at a low cost even buying used - there's nothing that can go bad other than a few O-rings or a rusty spring.
The twist-lock barrel was unique to AGD, and the quickest way to take off a barrel for a pull-through cleaning.
You couldn't do a pull-through with the barrel on the gun, and having an AutoCocker thread adapter was a lot slower to clean out even though it gave you a wider variety of barrels to choose from.
