Just got my new Mossberg 500 Persuader this week and after getting it home and checking everything out, I noticed all the slop in the fit of the stock to the slide tube. My Mossberg, I am sorry to say, has the ATI stock on it. I must agree with Liliysdad, this stock IS a piece of junk. To give you an idea how much movement (slop) is in this stock, I placed my shotgun butt end on my desk with the barrel pointed at the ceiling. Held the butt with 1 hand and grabbed the pistol grip with my other. I could actually move the barrel around in circles while the butt of the stock stayed perfectly still. Basic geometry (I guess), a little movement spread out over distance can become a lot of movement. Needless to say, I am very disappointed with this stock on such a fine shotgun. Mossberg should be ashamed for even doing this. I don't know if I should contact my gun shop with this problem or deal directly with Mossberg. What do you guys think? I know one thing for sure, however it comes out, this stock is coming off my shotgun and a quality collapsible stock going back on. Thanks liliysdad for the Mesa and CavArms info. I am also looking hard at the Knoxx SpecOps.
