mag spring
thingiverse
This is a spring for a 30 rounder pmag or any kind of ar mag. With this style of a spring you can just contain about 20-24 rounds in the magazine however if you make the magazine longer you could have the full 30 rounds in. I am up for idea´s to make it better. you can also use normal PLA or ABS or PETG however that will make your result different. Also a tip: put the spring into water after printing for some time like 1-2h after that the plastic is hydrated that will help the spring to be not that brutal. Thanks!
