WORK IN PROGRESS https://m.youtube.com/watch?v=fROermfFcFo Magazine mod for Adderini slingshot that uses 8mm ball bearing instead of arrows. Existed mostly as a way to clear the top part for more rail space (also because ball bearings are cheaper, i guess...) Holds 15+1 balls.

Either way this was fixed (sort of) by giving it another 0.3mm of tolerance - The mlok slot walls on the front was way too thick, which makes installing accessories very hard (if not outright impossible). It's now reduced by about 1mm, but I'm kinda worried if this will affect structural integrity, further tests are still needed Hardware is the same as the original magazine, but with an added extra m3x25, two m3x10, and a pen spring for the loading button
