I am game to test one out if you still need additional testers?

I have Valmet M76’s and would be happy to test and compare against factory mags, Tromix converted Weiger mags and Tromix converted Bulgarian Circle 10 mags.

My rifle is a 71, 1 have( 1) 76 mag I picked up at a Gunshow I have used for years .
The only thing I hate about my rifle is the ugly Snow White camo paint job .For the $900 I paid, I guess I can't complain. |

My M76 is my sweetheart and any mag for her is like buying jewelry for my wife. So I would love to test a mag or two but I would be really happy with ability to get quality mags at a reasonable price.

You many have to change it for select-fire guns, in order to allow room for the auto-sear to clear the side.
When I converted Weiger mags, I had to add an additional cut for the full auto guns. Tony Rumore Tromix |

the printed mags are designed based on measurements I took of a genuine valmet mag. This should allow full auto use right?

This is the second prototype, material used is down 35% and print time is down to 13 hours. This print is using my intended production material "NylonX" carbon fiber reinforced nylon.

I’m in for testing some of these million dollar mags when they become available. My Valmet M-76 is ready to rock!

I’d be willing to test ones let me know this is awesome hope your project goes well

Cool Project.
I've been buying Valmet mags for eons. good there. Still, very cool! |

Great project OP!
You're doing the Valmet collectors world a real service. Getting the feed angle correct would seem to be key since the Valmet has a different feed angle than many other AK designs. I have a couple M76's including a full auto and would be interested in testing one of your mags as well if you need another volunteer. If this project turns out to be financially viable for you, you may also consider printing Valmet .308 magazines. Original .308 20 rounders are even rarer and more expensive than the .223 mags. Good work! |

I'm sure it's expensive, but if the comparison is $250-400 per mag, doesn't that drop the minimum economic quantity a lot? |

OP, clearly you know what you are doing with CAD and 3D printing, but could you break down the economics of this in rough terms? I just have a hard time seeing how 13 hours at print, plus materials and losses to waste or defects is cost effective either, aside from the 6-12 you could spit out over a few days for a friend (unless that was the only goal). Obviously it's far cheaper than original steel mags, but isn't it painfully slow? How much would a set of injection molds cost to machine? I'm sure it's expensive, but if the comparison is $250-400 per mag, doesn't that drop the minimum economic quantity a lot? View Quote View All Quotes View All Quotes Quoted:

Some other magazines that are notoriously expensive to purchase and might be something for Regal_T-type to print include: H&K P7M13 pistol mags are going for $150+, Japanese Type 96 machine gun magazines currently $1200 plus, Beretta AR-70 30 round 5.56mm magazines are $65+ for used and $100+ for new |

This is correct, my cost to make one of these mags is roughly the same as the retail price of a Pmag. Not to mention the nearly 18 hour print time on my brother's crappy printer. Prints are done in Michigan and shipped down to me for hand finishing and assembly. I will have to ask relatively scary money for these at least until I can afford a faster machine. Hell if demand is high enough I might have to take out a loan and buy multiple printers.
I chose the valmet because I had ready access to a real mag and can easily undercut the cost of a real mag. For any other mag I would need a brave or kind soul to loan me a real one to take measurements and the willingness to test prototypes in their precious collectable. These are developed incrementally by trial and error. I'm an artist not an engineer. I have looked into home injection molding and the example of ones I can afford are not large enough. Making the molds is also a problem, while I can CAD design them I would have to go to my local machine shop to have them made. This is very costly and low on their priority list, I took almost 3 months of waiting to get a muzzle device I designed made, and the first one exploded. An update on the project: Mag now fits perfectly with no hand alteration required. Feed angle is now correct and it feeds without damaging ammo. The last issue i'm dealing with is, it seems the rounds sit to high up in the mag well causing the rounds to tip up occasionally when the bolt comes back. The next prototype should fix this. Once that's done I'll be printing off a batch for my testers so keep an eye on your PMs. |

Thanks for the update.
I’m guessing you’re making an anti tilt follower. The factory Valmet mags had a large lip at the front of the follower that prevented tilt as the bolt came back. In terms of keeping costs down, would it be possible to adapt Magpul AR followers and regular AR springs in your mag bodies? Mick |

Tapco gets a lot of shit and some of their stuff is crude and wonky but the bottom line is it does tend to work. I have heard a lot of good about their AK and Mini-14 mags.

Looks like you are getting close to the final design, my Valmet is getting impatient , LOL

What a great project, my hats off to the OP and entrepreneur extraordinaire.lol.
I am up for testing a mag. I will gladly pay for the shipping back and forth to help the cause. Please use the arfcom EMAIL system to reach me as the system does not notify me of new IMs for some reason. Thanks much, Tall |

Looking good man! I'm very interested in these as there is a M76 in the family. And because you are printing the. Looks like an Ender in the photo. Those little enders work pretty good for the money. What material are you using?
Looking forward to see how it appears works out! |

Hey guys Ive been gone for a bit but I am happy to announce that this weekend i had the first successful test of this design. 10 test mags are being printed now, i'll be ordering springs on payday. Keep an eye on email or PMs if you were one of the first 10 people to ask for them.

Am I first?
Attached File Attached File First impressions: Seems sturdy locks in tight to the magwell bolt retracts and rides over follower smoothly Follower seems to move in the mag body well without binding I haven't loaded it up and cycled rounds yet, but will probably get to that this weekend, and time and weather permitting, will run a full function test. Will let you all know how it works out. thanks for including me...this has all kinds of potential |
