Hey sonny, see u at work Thur. Needs me some free coffee.
M, PM sent. The LRP magazine that i can send u is rated at an OAL of 2.425", but i think i was working at 2.45 when i loaded them. It does require a special bolt stop since the base of the case is further back. I think u can see that at the very back of the magazine the aluminum (maybe it's steel?) is 1 piece. OK i'm looking at it now and it looks like the guy cut the back of the guide ridge completely out and made a new one piece ridge and slid it into the magazine. Then stamped it on both sides to hold it together.
There have been a couple companies that had an interest in making these at 1 time, but haven't heard anything recently. One told me it would cost about 100 grand to get machined up for it. But u know the guy that was making them oughtta' still have the machinery around somewhere...right?
