I have had this gun since 2009 and have put literally thousands of rounds through it and it still works like a charm. I give it a 9 out of 10 only because I've never had a perfect gun. It tends to spit shell casing with a vengeance. Also the thin line running down the mag that shows the ammo outs it as a .22lr. It used to bother me but now I kind of like it. The only I have had is that a couple weeks ago the bumber and the rod holding it in got bent. Getting a replacement has been easy and free. If not then i'll post an update. All in all I don't get why people hate on this gun, if running remmington ammo through it is a deal break then don't buy this gun. It works best with cci ammo but the american eagle/federals work too.
