I bought a remlin 336 after reading rave reviews and how awesome it is and blah blah
Well, if it was a remlin 336 and not an older production Marlin 336, there's your problem right there.
...and now back to the matter.
I must be living in the twilight zone.. or DPMS has drastically changed. My rifle was born with an A2 stock and no flash hider sometime during the AWB, so I really don't care if the castle nut was staked or not (there wasn't one). Most guys who tool around with their ARs long enough end up changing stocks, so this seems like a really petty thing to get on about. My carrier gas key came staked from the factory, although I do give it a very odd glance when these types of threads come up. I'm sure it's trying to fool me.
Like I said upthread, it's been a long time work gun, done plenty of training and classes as well as taken a few trips around the ranch on the mule. It's never had a significant failure with thousands of rounds over the years. Never thousands of rounds in the same day though. Honestly, I don't care if that will make it fail since it's never going to happen short of the purchase of a tactical wheelbarrow and a grant from Magpul. (although, I am open to any unsolicited donations of ammunition if someone really wants to know what will make my DPMS rifle fail)
..Guess I got the good one that came out of the factory and everyone else has Friday and Monday guns.
And no, it still doesn't have a flash hider
