the arsenal sam-5 5.56x45 AK has loads of cheep ammo at its disposal... but 80$ a mag and theirs no after market options.
this test mag body cost 2.30 cents for me to produce. when i have this project finished im looking at about 3$ for all internals + mag spring. im going to try and make this run on ar-15 mag springs since its common and same cartridge.
the final product is going to be modeled to look like AK-74 bake mags and im going to make different capacities other than 29 rounds in the end.
