Im sure there's a thread here...somewhere. I couldn't find any in the last year though. Has anyone had first hand experience? I have heard everything from light primer strikes to problems feeding but nothing recent. It looks like bushmaster is now selling a dedicated upper. I'm still thinking about it but I don't want to waste the money on a headache. Before anyone says "just get an ak" Ive priced it out and it looks like it could be a wash by the time I get an AK worth shooting. Any thoughts?
