    Magfed Minimag

    Stumbled on this on MCB and on Facebook. How is no one talking about this here?? This is amazing, I can finally ditch my clunky Dye DAM!!



    Sorry if this has been posted before; haven't seen a thread about it.

    Its very cool but that is an RT body, not a Minimag. The mod is like $345 and I would like to see some pics of the mods and the quality before I dropped that kind of coin but it is very cool.

    Sent mine off yesterday. Always wanted a first strike shooter but didn’t want to be gay and not shoot a Mag.

    Correction, you are right. He cut the end of the RT body to use an XValve.

    Anyway, I sent him a Classic mag to have it modified. I'm really stoked about this.

    Eh, it's just another mod for 'Mags...like Pneumag setups or stock class feeds.

    Full disclosure, I'm not really into the whole tactical/magfed/First Strike movement anyhow. Don't get me started with "sniping" in paintball. With multiple Army deployments under my belt I guess I've had my fill of that style and enjoy simple, fun, traditional paintball.

    But to each their own!

    Cool, opens up magfed games but at what costs? Granted it would be less than a Dam but the costs for the mags certainly outweighs that.

    Keep the blimp on the top. So much simpler

    while im likely in the minority i think its probably still easier to go with a fn303. first strike capable, cocker threads, magazines are tougher to find. It does open itself to 3d printed housings. especially since most people will be using a remote line instead gun mounted tank. if you wanted to do capture nuts then it would be doable.
    you do lose the option to have the level 10 bolt as the bolt is longer than a standard mag bolt.

    I'm in line. The more cool Mag stuff the better.
    The real trick will be getting a Mag fed mod that works with a pump.
    Somebody get on that.

    It's nice work; this had always been in the back of my mind but the metalwork kind of turned me off. It's a pretty... motivated mod. I mean you know it's srs bizness when the Tactical Tennis Ball comes out.

    If he's planning on doing this on a larger scale, I think it would be better to just suck the magazine receiver into a custom integrated rail. The receiver geometries are not that difficult to replicate.

    This is just a quick off-the-cuff mockup.

    You can also easily do other stuff like add “tactical” rails, fidget spinners, swappable trigger guards, etc. You're not just limited to Dye droppings.



    FN303's are no good for front players.

    Imagine that instead of running off break immediately to the furthest back bunker and sitting there the entire game, a player rushes off break and squats some prime real estate at the 50 armed with FSRs.

    Definitely not on the A-Team.

    This is really what I was hoping for: someone should mill a one-peice rail/magwell/trigger assembly (one that would accept standard M16 grips, like the old Nelson pumps from 20+ years ago). For $350 a piece, should be doable and would probably be sturdier, although his build seems to be strong. As I keep dreaming of it, I might still order a modified kit from him as I've always dreamed about a Mag-fed Mag.

    No need to mill it if you can just 3d print it (laser sintered nylon). Prices have dropped a lot for that service...





    So anyways, complexity is a Hell of a thing.

    As it turns out, the big $100+ blimp on top of the gun is actually a pretty complicated device. It's got custom molded funny looking private parts, motors, gears, sensors, microcontrollers, batteries, etc.

    It's just that the manufacturers have absorbed the blimpy complexities so all you have to do is cough up the scratch.

    And speaking of complexity...

    The current Automag pump mechanism interacts directly with the bolt, which in general is kind of cheesy. "All things should be made as simple as possible -- but no simpler."

    Instead, it should have interacted with the sear, in which case the whole thing again becomes a rail affair. It's pretty much the equivalent of a bolt carrier/delay mechanism in real firearms. Pump rod can be moved to not interfere with bottom-feed. And hey, as it turns out if you really wanted a nice bottom-feed gun, you have to mod the rail anyways. The extra meat necessary for the magwell could even be integrated with the pump rod guide.

    Of course, it requires someone else to suck all that complexity (like, 2 rods and 2 springs, plus pump rod) up into a rail unit, just like someone did with the blimps.

    Fn303 mags are easy to get, if you know the right people. Too bad i have no desire for a FN303

    I understand what you say but I'm not really interested in a pump mag for that purpose, to be honest. A semi would do it for me and should be simpler to build.

    Having said that and back to the first phrase on your response, I have two questions:

    - How sturdy would a 3D printed rail be, compared to milled aluminum? Sorry for the newb question but I really have no idea about the materials durability and strength for 3D printed plastic parts (even no-moving parts like these)
    - How much would it cost to design the part and how long should it take to do it?
    - In thinking a bit more on the idea of having a one-piece part with rail, mag-well and trigger assembly/housing, do you think it would be possible to retain the original body attachment screw, so that one would not need to mill a body and use new screws like he did on his project? If so, that would allow one to use ULE, Carbon or Tac-One bodies as well and would be really easy to assemble.

    Thanks,

    Mendel.

    - It's "sturdy enough for normal use". I still have my nylon printed rails from several years ago. It won't last forever like aluminum, but "half of forever is still not bad".
    - Dunno; I'm just a hobbyist. The rail part is already a known quantity, so it's just the magwell part that's in question. It's maybe an evening's worth of work. The problem isn't the CAD part. Not for an angry mob all armed with computers, AMIRITE?
    - The original body screw is in the paint path. It has to go. Even if that is fixed, I would not recommend ULE or Tac-One bodies for this. I tried to warn that one guy way back against modding a ULE body for FSR, and he didn't listen, and well, that turned out badly for him. Even if you cut the bottom feed hole, you still need to close up the previous hole in the breech. The entire thing is much easier with a classic body where you just use a mag to cocker adapter to rotate the breech.

    There are different ways to handle the frame screw problem, but the best ones involve metal work. That's always been the problem.

    Find the guy to cut the old neck off, cleanly cut the FSR feed hole and accurately put a second weld nut onto the body. And put me in for 2 if you ever find such a person.

    It’s $309 for the mod. But I guess after you factor in the shipping costs, . . .

    I’m not into the whole milsim thing, either; case in point, I use tennis balls for buttstocks and wear shorts and Hawaiian shirts during games. I’ve always been interested in magfed and First Strikes, though, and I love Automags as well as limited paint play. That’s sorta why I built this gun. I didn’t want an M4 lookalike that was way bigger and heavier than it needed to be.

    Not really. DAM magazines are about $10 a piece. I carry 8 magazines on me.

    A bottom feed Mag has been on my to-do list for years and the Magazine feed looks like an interesting engineering project. However, currently I have a full plate that pretty much takes up the rest of this year. If there's actually a market for it I would take the project on, I pretty much know the direction the design would need to go to make it work, completely doable but a lot of R&D.

    One of my favorite guns of all time was a springfed pistol automag. I'm looking to build something similar again, but with tpx magazines. Springfeeds are just a gong show when time isn't on your side.

    Flash back to the seventies, back to the days when we only had one TV channel, KNAZ out of Flagstaff AZ (NBC). Man I had completely forgot about those characters, what a trip looking back at that.

    Please let me know, then. I'll keep an eye open anyways. I also thought that maybe a Unibody design could work even better but then it would probably make it much more expensive, right?

    A Uni-body makes the most sense to me. All the basic Automag specs would have to be reworked and worked around so engineering it from scratch makes the most sense.

    There's a reason why this is the last project on multiple people's lists. It involves the most (re)work. So hats off to anyone who gets it done.

    My recommendation is for the angry cloud of monkeys banging away at their keyboards on the forums to bang away on their keyboards in a slightly different way, in cooperation, to produce the rail+magwell design. Because computers can be used for more than just posting on forums.

    Then, when you do find the mythical unicorn, everyone will be ready to go. You don't really need a modified body to design/test a magwell, and again the automag rail is already a known quanity so you pretty much don't need to mess around with that. The rotating breech is also a known quantity available from multiple sources.

    I suppose you could leave the breach and rail as is and just move the frame to the top side and use some type of pneumatic system to trip the sear.
