Folks, I must apologize in advance, as I know there're a few threads regarding detachable magazines on here already. I didn't want to hijack anything, so I started a new one. So, that said, here's the deal: I've been working on a design for a detachable box mag for the Mosin Nagant that does not involve alteration of the original rifle, and works as a true, modern mag...push-button release, spring and follower that stay in the mag body when you change mags, etc. I've come up with several designs, but haven't been able to work on any due to trips overseas and a really packed schedule. Well, my wife and I just drove cross-country for a job-related move, and somewhere in Montana all the pieces fell together! My design, in a nutshell, uses a modified "Lower Receiver" (ie, an original or Repro Mosin Mag), and thus allows the use of a modern mag, without having to modify the stock or the upper receiver. Here's the issue...I won't be able to even start fabricating a mock-up for a while, and I really can't spend hours trying to bring this thing to life. I'm wondering if anyone knows of any Mosin parts fabricators that might be interested in checking out my design. I'd prefer a small fabricator with a good rep, because my plan is to just pass the design onto someone that can produce it, get it on the market, and make some money. All I'd really like in return are a few finished units, and maybe some parts for my other Mosins What are yall's thoughts? Anyone you've done business with that you'd recommend? Oh, the only real requirements are VERY basic metalworking tools...if I go it alone, I'll be using nothing fancier than a dremel. Thanks, Folks! ***Edit: Forgot to mention that my design does not rely on the original floor plate catch, which also means that it could be modified to work with a lot of older rifles. I also have seen Mosin mags for as little as $2.00 each, so a fabricator could do something similar to what Mr. Josh Smith or Smith Sights does, and either modify someone's existing mag, or charge and extra $10.00 or so to just ship the person a new mag, letting them keep their original part intact and unmodified. Thanks again!
