Not too sure if this is off topic or not, since this IS the great outdoors, I figure it would see the right people here. Don't know a whole lot about this thing, I got it in the purchase of a few different items. I can do more checking, get specific numbers, etc., but it appears to be pretty complete. It's a 600. 99% sure it's 12 gauge. I'm only vague on this stuff because I'm typing this at work and it's sitting in my garage. I will gladly get specifics if anyone wants them. Maybe $50 for it. PM me if interested!
