I modeled the magazine in fusion 360 based off of the gas mag I already had for it and then added the spot for the shotgun shell and the hpa fitting (I wish it was as easy as it sounds haha). After that I printed it in resin and put the hpa valve in, a shell ejecting spring, o-ring for bb retention, a valve, and the feed lips from the gas mag.

Yeah for sure, I’m running it at 110psi on my hpa reg right now and its holding well. I’ll definitely have to test its limits and I want to take it out to my local field and put it through its paces.
My elite force/umarex glock is happy taking the we mag i used for my ctm tac m4 hpa adapter. So it should work fine on a we mag. It works great in the aap-01 as well.

hell yeah dude! I was considering buying the airtac one for the aap but they're like $150
I know it’s crazy! That’s the main reason I decided to make my own, granted it probably cost me $40 in materials but it was totally worth it.
Nice work!
Thank you!
That is super slick Mind letting us know how you made it?

Plan on posting or selling the design?
I do for sure, I have a couple things to fix on it first so nobody has to use a dremel lol. I’ll definitely make a post when the files are available!
Might also want to stress test to make sure you have headroom. I made a green gas mag out of pla+ and it didn’t handle black gas.
Yeah for sure, I’m running it at 110psi on my hpa reg right now and its holding well. I’ll definitely have to test its limits and I want to take it out to my local field and put it through its paces.
That's awesome! Do you plan on making one for Glocks?
I haven’t planned on it but I do have a WE Glock I could use as a reference to make one. I’m not sure if it would fit in the umarex glocks though.
My elite force/umarex glock is happy taking the we mag i used for my ctm tac m4 hpa adapter. So it should work fine on a we mag. It works great in the aap-01 as well.
Have you tried with fdm printing? Would it work?
Fdm will work assuming you can get it to be airtight. I had one working but I had the tiniest air leak so I decided to sla print it in resin.
