aap01 magazine follower
This is a modified magazine follower of the stock mag that comes with the aap01 airsoft pistol. I made this to address the issue where the bolt doesn't lock back after the last round. I printed this in ASA on an FDM printer, but it might require something tougher, like CF/nylon or CF/PC.
