I bought one for Christmas. I sold all of my chokes and shims on ebay for $55 and ended up buying a Carlsons extended range choke for ducks and a Jelly Head for turkey. I will say that it is a great gun. It won't cycle the light federal 2 3/4 shells out of the box. It might after a break in period. But it cycled the slighly heavier 2 3/4 winchester low brass loads no problem. I stuck the recoil reducer in with a flat head screwdriver for duck season. It helps a little when shooting 3's and larger but won't cycle low brass. It cycles great everytime while duck hunting. When you first receive the gun, be sure to wipe all of the grease out of it. Mine had a ton and would have frozen in our winter temperatures. The ONLY con I have with this gun is that's it's a little heavier than other auto's especially with the recoil reducer. It alone adds almost a pound. Not a big deal though. And the release button is quite stiff. But it is a great gun especially for $650 which I paid for it. If you have a budget and want a GREAT gun, I'd say buy this one.
