I purchased 20 ga auto 4 yrs. ago and have since fired 1000+ rds. with no problems. Have only cleaned a few times when action starts to stick after hundreds of rounds and dirt/sand causes problems and then it works like new again. I lay this gun in the dirt / sand and drag it thru the brush, I don't baby it. I own many other shotguns and have shot many others. I love this shotgun and enjoy shooting it over many that cost 5 times as much. I am getting ready to buy the same gun in 12 ga. and maybe a back up 20 ga. so after I wear my first one out I don't have to worry about finding another.
If your having problems with this shotgun, try cleaning it and spraying oil every where you can. Then work the action 50 times to make sure everything is lubed. Now go have fun. If your having problems ejecting shells, check the O ring to make sure your not loosing pressure. Oh, let me guess. You didn't know there was an O ring.
I've shot this gun too many times for it to have manufacturer issues, if they had problems something would have developed by now.
good luck and for the price you have nothing to loose.
