>are you thinking about slapping a BAR magazine onto a Mauser?
I'm thinking about a magazine-fed rifle that can accomodate as many different cartridges as possible. Of course the best solution is to have a replaceable magazine well, so that people can buy e.g. FAL or G3 magazines if they want to use 7.62 NATO. But making a rifle that can work with different magazines means that the maker will have to either ship it without magazines, or have a stockpile of completely different magazines. A third option is to have a default "do-it-all" magazine, and offer different magazine wells as an alternative or an extra, if you are feeling jewish. My idea is to make a magazine that fits into the BAR's magwell, but it's designed with a set of spacers and followers, so that you can set it up for shorter cartridges. Preferably it would only need a spacer, to shorten it down for 7.62 NATO, because a shorter follower with its spring should be able to push up longer cartridges too. And if you prefer .30-06 you can still use standard BAR magazines as an alternative to this propetary magazine.
Do you think it's a viable idea, or is there an obvious flaw that I just can't see?
