Remington Feeding/Ejection Issues
I've had some problems with new(er) Remington semis, both the 7400 and the 750. The most common seems to be that Remington neglects to tighten the long barrel nut and this causes the barrel to wiggle back and forth on the receiver. This causes all manner of feeding issues, but if you realize what's happening it is easy to remedy by tightening.
The basic Remington designs are very good, but manufacturing quality control is definitely a HUGE disappointment with Remington!!!!!!
Chambers are often machined terribly sloppy and very crooked, as evidenced by the wonky shape of the fired brass they often spit out. They look like Lee Enfield fired brass out of a wartime manufactured gun. I have measured some factory new chambers with head space gauges whereby the action can be fully closed on a no-go guage.
Another issue I have had very recently was that the bolt face on a new 7600 pump was machined incorrectly, thus causing the gun to have major extraction problems every single shot. (Please note that the 7600 and the semi version are almost identical in parts and design, save for the minor alteration of gas operation vs pump, ergo why I'm discussing the pumps as well in response to the original poster's semi-auto question)
And yet another observation is that Remington can't seem to drill the scope mount holes straight. I've had this occur on a new 7600 as well as on a model 700 I've purchased new over the last 3 years.
Improper sealing of wooden stocks also seems to occur whereby wet weather swells the stock at the butt end and makes the smooth wood contour look and feel lumpy.
IMHO, the manufacturing line is turning very good designs into piles of sh1t far too often.....
If there were isolated incidents of manufacturers defects, that's pretty much a fact of life, because mistakes do get made and sometimes slip through quality control but the recurring theme of the same problems is one that Remington absolutely needs to address.
Most folk are smart enough to understand and accept guns being built to a price point where fit and finish can not and will not be that of a big dollar custom, BUT it's NOT acceptable that they f**k up the very simple basics on a frequent basis.
Now that I have that off my chest, if you find a Remington auto that doesn't jam, then hang on to it.
RANT OFF. (And I apologize for somewhat hijacking the thread)
