To go along with that, I'd wager a paycheck that a good chunk of those accuracy complaints could have been traced to deranged sights with a thorough investigation. (Yes, I'm the anon from the other thread, and I'm the guy that had to deal with weapons with accuracy issues, and it was usually damaged sights.) There were plenty of other things that could cause a wandering zero, but the sights (specifically that shitty front sight mount) were the most common cause. There are other things that can go wrong with dedicated match conditioned weapons but that's not what we're talking about here.
>bullets contacting the flash hider
Maybe one in 30 or 40 rifles, as received from Crane, which is way the fuck too much. It's not a problem with NM spec flash hiders, which are simply reamed wider. The basic issue one was too tight. You could actually eyeball these on the rack because there would be streaks of gilding metal on the interior of the hider. I saw a deadlined one from USS Sacramento that had been severely damaged by a bullet strike, but only one of hundreds. Usually it was just a graze. Some of these would actually group okay, but the group would be so far off from point of aim that the sights couldn't compensate for it. That's technically a manufacturing issue, but really it's a design one.
>wooden stock fuckery
The rifle was designed for a plastic stock from the start, but initially they couldn't make a good one. They eventually did. They get a pass on this and there's no reason to deal with it today. Wood for show, plastic for a pro. The trigger assembly's clamping pressure will still fail over time and fuck your zero up with a plastic stock, but that doesn't happen overnight.
Again, not deal breakers for range toys, but this was (and should have been) unacceptable for service rifles when the M14 was introduced.
