3d printed Tikka mags (not just 223 anymore)

[Dioni A]

I’ve got a printer and a bunch of tikkas if you’re wanting to check fitment. Are you ok with sharing the .stl file

 

[pods8 (Rugged Stitching)]

@pods8 (Rugged Stitching) you should take a wack at developing a 3D printed AICS Magnum mag with a 3.56" COAL for all of us that are rocking Tikkas in an XLR/MDT chassis and have no choice except the 5rnd metal AICS mags that weigh a half a damn pound! I would definitely be willing to invest some money/time/effort into dev of that!

In the mean time I will keep trying my luck at trimming down/cutting apart other poly mags to get them to fit...

I don't have any of those items (mag or chassis) to be very productive on that front.

Sent you a PM

Received these today from @pods8 (Rugged Stitching)





These will go through the paces here in the Arizona desert and Wyoming mountains this spring/summer.

Initial thoughts…

The bright orange is great for hunting items as I’ve stated here quite a bit. When you shoot often, and in the heat of the moment, shit can get misplaced easily. Or you have a messy truck or jeep full of gear and are looking for something specific. Bright orange makes things easy to find.

The texture on the side walls of these is a great feature.

The stamped, easy to see, magazine type (M+, 223 etc) is probably my favorite feature. I am constantly marking mine with paint pens, so this is a great feature for someone who shoots lots of guns often and in different cartridges.

They will hit the field this evening for first tests.

A: 2.905
B: 1.356
C: ?
D: .557
E: .420
F: .445

My current load is only 2.931 so I hardly need much more but I'd probably go a little longer for future needs. PRC length of 3.07 might be about right.

Sent you a PM to try out.

Ideally that material holds up to wear and tear, heat, etc. cause there are limited options that retain bright colors that still are stiff, reasonably temp stable, etc.

I'm gonna try another variant with carbon fiber but its in black but that looses out on a major perk of the color.

It will be 110-120 here in another month. 2023 we had 30+ days in a row over 110. If they survive here, heat wise, they’ll survive anywhere else on earth where someone plans to shoot haha.

If these flush mounts work out I’d be really interested in a set made of carbon fiber

To clarify its tiny carbon strands in the filament, which being black limits the colors they make filaments with carbon in, often only black but sometimes some dark shades too. The orange ones have glass fiber in them which allows for more colors since its clear vs black.

 

[Foster_65]

I’m fine with black. I could duracoat the upper portions blaze if it works out.

I might have to get into the 3d printer game. I’m not very techy but my kids are decent at it. They had a couple classes in school and I was having them print be a few things until there teachers figured out they were printing gun parts they put a kabosh to it. Now I’ll have to maybe pick one up. It blows my mind what folks are doing at home with these things.

They’re fun but pay attention to brands. At the end of the day most any printer can print well, but you might spent ALOT of time tuning and modifying to print well versus just printing.

Think of it like there are cheap finicky rifles you can spend a lot of hours and components on to get shooting well. Some others shoot damn good out of the box and you can spend time shooting versus troubleshooting.

Also some of these filaments when you aren’t printing trinkets need higher nozzle temps, hardened nozzles, higher bed temps, heated enclosure so they don’t warp, give off toxic fumes so you want to vent them outdoors.

 

[goathunter]

Well my PLA prototype failed. The top didn't print right, it's all warped. I had an error about an "unsupported" something - change orientation or add support that I ignored. Maybe I'll try again with adding supports. Seems like it would print nicer if it was orientated with the actual bottom as the bottom while printing, if it would stay in place, if that makes sense. I also think I'd go a little wider internally (it's pretty tight) and longer COAL. Also need to read up in this thread on the status of magazine springs. Are you robbing your OEM springs?

 

[pods8 (Rugged Stitching)]

You should be printing it upright, please flip the STL to be bottom down, sorry that wasn't clear. That is how I've been printing them. It probably won't be as snug when you change the orientation. COAL can be changed though it needed.

The model file exports on its side and due to various compounding sketches as I have modified things I don't want to flip it. Eventually I can correct the orientation of the STL but with work in progress I didn't think about it since I knew to flip it and didn't remember to mention it.

Well, what say you?

Well, what say you?

I used them yesterday evening and this morning…

I was able to swap in my M+ spring and follower without any fits. Liberated a spring from the 1 million factory Tikka 223 mags that I have and used the supplied follower for that one.

Both magazines snap in cleanly with both factory and high desert bottom metals. They remove fine but are “stickier” than factory. Once they break in with dozens more “in and outs” I think this will be relieved. Nothing detrimental here.

The 223 magazine feeds and functions great with black hills 5.56 ammo so far.

The M+ magazine with 260 Rem and 22 Creedmoor grabs the cases a little tight compared to factory. This is noticed when loading rounds into them and potentially noticeable if a user limp wrists their gun when cycling. I cycle my bolts harder and faster than most and there was no issue there. More deliberate testing to be done.

This is super preliminary at this point, I’ll send more feedback after more use.

Also another note. The spring swap on the 223 into the provided follower was TIGHT. As in, slightly shaving plastic with the metal spring as I slid it in.

My bad, thanks. I'll try my luck at tweaking with the other application you mentioned.

Maybe thin the wall thickness a hair to give more clearance? It’s probably the slightly rougher surface of the glass fiber filament versus the smoother factory mag surface.

Yeah that I was aware, was using thicker walls like that OP model to help stiffen the upper feedlips. 223 doesn’t give a lot of forgiveness if the walls flex out much compared to larger diameter cases. It doesn’t leave much margin on that narrower follower to inset the spring.

Could be. I’ll do some more messing around tomorrow.

10-4. Not a show stopper.

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 flowing.
