I have this old Tippmann A5 converted with a Tacamo to accept magazines, sadly the magwell received the round head magazines. I wanted to updated to more reliable ones, so wanted to buy mcs ones... they are out of stock since forever.
While looking here I found Untangle (https://www.thingiverse.com/Untangle) great work, and with a little of fidgeting on my part I came up with the Tacamo base and then added his DMAG receiver.
Quick and Dirty but works
Also modified the locking mechanism as it didn't quite fit with the old air input
EDIT: Gave it a little extra room around the old air input to the magwell
