I would like to get a 7 shot Choate magazine extension for my 870 and Bushmaster is out of the parkerized versions and they have no idea when more will be available for shipment. I prefer this model because I had one on one of my other 870's and it worked great, very relable and durable. Anybody know of any distributer's that carry this or can I order directly from Choate? Do they have a website? Any advice and comments apreciated, thanks, Terry
