3d printed Tikka mags (not just 223 anymore)

[pods8 (Rugged Stitching)]

10-4. Not a show stopper.

Its kinda a one and done thing (esp if an alternative follower spring source is found versus borrowing one). There might me some minor tweaks I can make to fit it a little better, I just didn't spend too much time on that part yet cause it goes in despite being tight. Plus in the US we're probably more likely to get a US fractional width spring, if we find a source, vs a metric one, 3/8" would be just a hair narrower than the tikka one.

I just went and played with one again, there is decent side to side clearance (a dummy round in a mag without a follower in it moves around freely). Could you describe more what you're noticing?

I've noticed when loading rounds its helpful if I push down on the rear of the case already in the mag so the follower slides down evenly (versus the rear hanging up a tiny bit), is that by chance what you keyed in on? Otherwise the ones I have here I am not readily noticing much drag while loading rounds into the mag.

Anyways keep the candid comments following.

I’ll take a video at some point showing loading the factory mags and then loading these. A lot easier to see that way then to type out a novel like I normally do

Only thing I can notice is if going really slow the 3rd round nose (eldms in the dummy rounds) can get bound a tad. I just compared some measurements against a tikka M+ and tomorrow I'll try moving the rear wall forward .3mm and pushing out each interior wall .1mm. Other than the surface finish difference that is about all I can notice as being different.

I would be interested in trying out one of the flush fit mags for my PRC. If you pm the .stl I can print one and check the fitment.

Like other have mentioned, a 3D printer would be nice....

If you make your own springs, figuring out metal feed lips would be nice!

I have a few plastic AR mags that have metal lips, they're nice!

Moving the side walls out seemed to make loading rounds in a tad less friction so that seems like a good change. Moving the rear wall up a tad didn't make any difference but I'll leave that change since it works either way. The 3rd round would still get bound up with the tip catching the front wall if I pushed the second rounds out SLOW (if fast the jostling wouldn't let that eldm tip grab) I sanded that with some 220 and then 500grit sandpaper and that seems to have solved that. Its just a function of the glass fiber filament having a bit of a texture to the surface.

So that is solvable if folks run across that.

Printing a custom follower with a little bit of a ramp up front (like the 223 one) probably would prevent that also, I'll experiment with that at some point.

Why not try a different type of spring setup, maybe 3 or 4 coil springs in a row, that would just need shallow divot holes to locate the springs under the follower and in the base.

The orange flush mags look great. Didn’t know I needed any until now haha

Anything/everything is a possibility for those that want to experiment. At the moment I've been mostly focused on dialing in the bodies and seeing how this material works in the field as a foundation to build upon.

That said the factory style spring allows for a solid bottom and you just insert the follower and spring from the top, makes for a less complex and stronger print. If doing something like that you'd need a removable bottom and all that would go along with it. Not trying to deter anyone, just pointing out the considerations that have crossed my mind.

This is a 223 tikka 4rnd magazine spring next to an MDT aics 223 magazine spring. They don’t sell replacements from what I could see, but if the accurate mag is similar this should work. Might even be able to cut into two springs.

The coil springs would work fine with a solid bottom and they are widely available for just a few cents each

I mean the bottom and body being one piece, it seems like it would be hard to insert a follower on a diagonal in through the top while keeping all the coil springs in the right places. It would likely need a two piece body so the springs could be inserted from the bottom was what I was trying to convey.

The W shaped factory spring attached to the follower you can thread in though the top and it settles into place.

Would you mind sharing the stl with me? I don’t know what I would use for a spring yet, but I’d like to give it a try. Thanks.

Any new updates on this endeavor?

 

[pods8 (Rugged Stitching)]

I which context? There were lots of different tangents going on and folks trying various models, etc. No replacement springs yet to my knowledge. I believe the petg-gf has been holding up fine. I imagine @mxgsfmdpx has probably put the most rounds on any and could comment more.

I goofed up my latest 223 model trying to get the follower to fit the spring width better and it stopped feeding well so I am reverting and need to sort that out. I also ordered a larger diameter nozzle to try printing with to see how that turns out also.

Yes sir.

Between 260 Rem, 6.5 Creed, 22 Creed, 243 and 223 the magazines that I have are somewhere around 6,000 rounds ran through them.

Still functioning as expected and I don’t have the intermittent feeding issues with the 223 that plagues the recent 223 Tikka factory mags. They did require a bit of “break in” for full transparency as they were tight when new.

@pods8 (Rugged Stitching) did you end up making the .1mm change to the wall we discussed? I think if that change makes it to the “production” units there will be no “break in process” at all like mine had.

any context really! this thread is awesome and i checked back in on it i hadnt really seen anything new so i was curious if a spring solution had come out or just anything new and fun really!

pretty sweet that these mags are working well!

Yeah I tweaked the M+ wall thickness right away after we discussed it to test it out.

Generally working well. Little tweaks here and there help improve or in the case on the 223 change that caused feeding issues it can hurt things too.
