I wasn't putting down mossberg, just stating my history with them. I've had problems with my Remingtons also.

My moss 500 was bought simply as a gun that I wanted to play and hunt with, and more importantly, it was cheap and I was young and didn’t have a lot to spend. Once I got serious about hunting, I found that this gun was loud. Lots of the parts in the fore grip shake when you move the gun. It was impossible to carry it quietly, so I got rid of it. I bought another Mossberg to replace it, but this time a slug gun. It shot to the right. About two inches at 25 yards and got really bad further out, so I got rid of it too. I now own an 11-87. I don't like the safety on the Remington as well as the Mossberg. I don't think putting your finger near the trigger to operate it is a good idea, and even more so with gloves on while hunting. I always feel like I have to look at the safety or I'm being unsafe. Further, my gas ring has broken on occasion while cleaning. Open it up and it's broken. Never had it not cycle a round, so I assume that I'm doing it while I'm breaking it down, but I have to keep extras just to be sure.
My son got an 870 youth model 20 ga. from Santa this year. On the rear part of the vent rib, the raised checker flares up on the right side. Once you're used to it, it doesn't seem to make a difference, but it is poor machining/quality.
All I'm saying is, find what you like/want, which may be the Mossberg, and that is fine, but if you find thatyou'd prefer something else, and it costs more than you have to spend, then be creative, wait, save and go get it. That way you won't have to change them later as people like me have done. They say smart people learn from other peoples mistakes, I'm just sharing mine.

Good Luck and enjoy,
