So a couple days ago I had an issue while attempting to reassemble my Mossberg 590SP (50645) after field stripping. The barrel wouldn't go back in. It'd slide and then clunk, no movement. After about a half hour of study, I figured out the ejector has a tab that slips into a slot in the barrel, and this tab had gotten slightly mushroomed (probably from indiscriminate banging when sliding the barrel back in). I smoothed out the ejector tab and the corners of the slot in the barrel, and it went in fine.

I've never heard of this issue before. Anybody else hear or experience it? I thought Mossbergs were supposed to be soldier-proof
