Re: Moss 590A1 Ext
kmc0929, I have a Choate Mag Extension Tube on my 590A1 that adds 2 rounds to the mag tube. I got it from Midway and the product # is 639840. At the time, 8 months ago, it was $42.99 plus S&H. The product info that it is listed under says its for a Mossberg 835 but my research prior to buying indicated that the tube threads on the 590A1 and 835 are the same and so far I've had no problems with mine. Used it at a basic shotgun class at Tiger Valley a while back with no problems. The only issue with the extension, (and it is a small issue) is that the mag tube is now 1.5 inches longer than the barrel. But,I've been considering getting a 20 inch barrel for my 590A1 anyway.
