3D Printed Magazine Body Extensions – FAQs, Requests, Reviews, Feedback

I've tried it with the gen 1s, but due to the design of the magazines, the bodies of the extensions are wider than the magazines bodies. Imagine the baseplate of the mags, just extended. They looked rather chunky. It didn't seem too practical to me, so I didn't make them available for sale.

I see your point are you willing to take another look at the Gen2?

It's my understanding that the "base plate" on the Gen 2 slides off, what about incorporating the base plate into the extension? if that feasible?
 
I've not seen a picture of a 7.62x39 lar mag with extension. Have you made these yet? Awkward mags are one of the downsides of this cartridge/magazine.

Edit: Found the pics!

That is essentially what I made.

Because of the increase in thickness for a baseplate that attaches from the outside, the extensions would be too wide to fit in most pouches properly (try inserting your mags base first into your pouches to give you an idea of whether it would work for you). The size of the extensions would put the cost in the $20+ range, meaning total cost for mag + extensions would be getting close to genuine AA mag pricing.

If you really want to buy some of these, send me a PM.

Have you made a cover for the 25 round 10/22 clip yet?
Also wondering about the xcr-m 10 round mags.

I have only been able to get my hands on the 5 round XCR-M/AR10 mags, can anyone confirm they're the same shape as the 10 rounders?

Might be ignorant, but why is it that there aren't such things as a 10/20 or 10/30 pinned pistol magazine? I mean, you can get a glock with it's magazine pinned to 10, so why not an AR style magazine, designed for the AR pistol, pinned to 10, but the full length? Clearly there is some (stupid) reason for it, otherwise these mags would come that way too!

Just curious.... I'm considering getting a few of these for my AIA mags, as they are just a little bit short - can you make them in custom lengths if one wanted? I wouldn't really want the full 20 round mag length, maybe something about half as long for the extension?

Well, unfortunately the laws and regulations in place now are a rats nest. It's probably best not to try to try to apply logic to them. Sure I could do a custom length, just PM me what you're looking for.
 
These new M14 extensions are excellent. Much, much nicer for mag changes with the AIA-type mags. Can't wait to get them out to the range. They should make the 5/5 mags actually usable, too.




Got some red extensions for my XCR 7.62x39 mags, too. This pic makes them look really orange, but they look like the red AIA extension in the second pic.

 
All extension designs have recently been revised. Up until now, the extensions were designed to replicate a PMAG 30 type curve. Now they are based on the USGI 30s.

The 20 round length extensions have also been updated to match USGI 20s (Type 2 LAR, XCR-L) or Bushmaster 20s (Type 1 LAR).
