RE: "lightweight" aluminum recievers
Bob, they aren't made out of "aluminum"!!, it's an "aluminum alloy", meaning several other metals as well, which is a very strong material!!! The lock up of a shotgun is in the barrel end and the bolt. So it really doesn't need a solid steel reciever. Another point is this, if a solid steel reciever is so much stronger compared to the aluminum alloy ones, why doesn't Remington's shotguns come drilled and tapped? I wouldn't worry one "iotta" about the strength of these aluminum alloy guns compared to the solid steel guns. Browning, Winchester and Benelli, all have aluminum alloy recievers, and these are some of the top rated guns on the market. Better balance, and carrying weight are the two main reasons they went this route. If they weren't able to stand up to the stress put on them for shooting those 3 1/2" shells they wouldn't be selling them!! Mossberg has been making their guns for years out of this material. Your fears are unfounded in my opinion.
