Zero aftermarket support. The only website that sells parts for it is non-responsive (it will take your money though, you just never get your order). Collapsible stock is near impossible to find, and when you do, they go for insane amount and in terrible condition. That's not really the worst of it. The lever safety model has had a recall, as it can fire when switching to safe. There's no replacement for upgrading to safer cross bolt configuration. Also the internal buffer needs to be replaced after a number of shots, and guess what, no one makes those either. That was actually the part I was trying to buy from the website. Like I said, there's absolutely no practical reason for anyone to own one of these. If you have one, you are pretty much not going to shoot it.
Yeah this is pretty much all the information I've arrived at, but I'm too stubborn to use logic to avoid buying this platform knowing the above issues. I think this would most certainly be a safe queen for me, and I'd only take it out once or twice a year to shoot a few rounds.
Regarding the site that you referred to taking your money I keep reading mixed reports on the person operating it. Some say he does deliver the orders, but due to a single person operation it takes a while. Then I find people that have experiences like you, where they take the money and are unresponsive with shipping out products and returning correspondence.
