So I got an STG58 a few weeks ago. Great gun, but I'm having an issue with a new magazine I got yesterday.
Every 4-5 shots, it produces a failure to eject, then closes the bolt on the expended round, but the bolt carrier does not close all the way. It stays open about a half inch.
My plan is to replace the follower and spring with one from a working magazine. Then at least I'll know if it's the body or spring or whatever isn't working right.
Anyone else here ever heard of this problem?
