The Revo’s 1st Printed High-Magazine Clips – Courtesy Of Greg B!

Our very-own Greg B has printed The Real Revo’s first ever “high-magazine clips”! These are pictures and notes on the rough draft, as presented to me:



But still need to do some tweaking in the interior dimensions of the mag itself.
Just a hair too small for the rounds to feed smoothly.
The curved lips are a bit too thick as well.
I may try printing them without the lips, leaving a narrow channel to install metal ones.

Also playing with the idea of totally re doing the computer model & adding some features that will let the mag be used either in an AR or a Mini 14.
I’ve got an old Ram magazine that work with both platforms, so it should be easy to reverse engineer.

Close up of the follower installed. It slides smoothly.


Just another view.
Also shows the machining I did for the FCG.

They fit into the lower like butter.
I got that 80% lower from Sure Shot.
Thanks for the tip on them. Managed to get it right before all hell broke loose and everything was sold out.

Thats all for right now. It’s still a work in progress, but I’ll get it sussed out.

    I have a few notes and questions that I’d like to add. I didn’t want to detract from the post.

    1) “Harvester of Sorrow”. I absolutely LOVE it! I’ve listened to that song a 1,000 times and never gave any consideration to what those words meant. See, guns are educational tools, too.

    2) Have you considered using a dremel, etc for the curved lip problem?

    3) What kind of polymer was used? How sturdy are they. Do they feel solid?

    4) Do the ridges on the inside of the mag cause the bullets to drag as the follower moves up?

    5) Glad I could help on the lower. 🙂

    6) Directed at everyone who reads this: Revoistas are actively working to secure our future as free citizens. What have you done for the cause, lately (even if it’s just passing on knowledge)?

    ABS plastic is the material. I think it’s a better choice than PLA. Which is very brittle. But ABS isn’t indestructible either. I was able to make the layers split with a decent amount of force. But, an application of superglue fixed it right up.
    My issues right now are the interior of the mag is a bit short in the long axis. Regular FMJs just fit, but only with a few thousandths clearance. I have some red tipped Vmax rounds that ain’t going in. No way, no how.
    The thickness of the curved lips also don’t let the rounds sit quite high enough for clean feeding into the chamber. I could try trimming them with a Dremel or some other rotary tool, but the way the layers are stitched together might make it wonky. The machine puts one layer down in the long axis, and then stitches across the short axis. The the long axis, and so on and so forth.

    I decided to have the engraving as simplistic as possible. Kind of got the idea from the old WW2 warbirds. Kinda goofy, I know. I was tossing around a couple ideas in my head about what to put. Flipped a coin between “Dead Man’s Party” & “Harvester” just kind of making the rifle unique to me. If prices mellow out in the future, I will probably build another.
    I’d be happy to give any other info I can. I know I’m leaving out stuff. Blame it on the PBR.

    Greg! Wow!
    OutSTANDING sir!
    Damnit man, now I HAVE to get one of those printers. How costly is the polymer ‘ink’?

    When this shit is refined and cheap, the world changes.

    You guys are killing me with “high-magazine clips”. Somebody is going to think you’re serious.

    I got a lancer mag just to check it out, as one of the local tac shops really pushes them over the pmag. The lancer uses metal feed lips with a polymer body. The problem would be how to fab the steel lips.

    The mags look great! Well done.

  6. Locke n Load says:

    BTW Greg, those homestyle tattoos.. remind me of HS.
    Another troublemaker I see… Alcohol and attitude didn’t serve us all well, did it 🙂
    Liked the ‘nuke’ on your thumb webbing tho

  7. Greg B says:

    Thanks everyone 🙂 this project is really a lot of fun. And useful too.
    I’m going to keep refining and should be able to get all the bugs worked out. I knew it wasn’t going to be perfect right out of the hate, but I will persevere.

    I think Nota was being tongue in cheeky with the high magazine clip thingy.
    As to metal feed lips, that would be easy peazy. But I do have a machine shop in my garage. BUT, a pair of tin snips, hammer & a vise can do a dump truck load of work.
    At the risk of sounding like an asshat, seriously, think about what the people who came before us used to do with hand tools.
    Anyone, and I mean anyone can learn to work metal. Whether with hand tools or machines. It really isn’t that hard. (No pun intended)

  8. Greg says:

    Okay, that does it. I need info on how, what, etc… to get to print these works of art. Or, have a missed a link here in the files?

        Makerbot’s newest model, the Relicator 2 runs about $2200. And a kg spool of ABS cost around $50. But you can print a whole lot with one spool.
        There are other options like the Rep Rap, the Printbot and tons of DIY kits and plans.
        Funny thing, I found out the guys at Defense Distributed were using a Stratasys printer. Which is an industrial unit. Apparently they were leasing it and the company got their panties all twisted up when they learned that DD was using it for the printed firearms project. So they repossessed the machine.

    Hey Greg, When you going to get these hi clip assault magazines ready to export. (out of your garage) I have a salt gun that might like to have one. by the way anybody happen to have any extra 03-a3 clips? Just wondering
