Is this your first AEG of AR-15 type?

Having wobble does'nt make that problem because I have a little wobble in all of mine and they work everytime.

Do your other magazines that dont fit all slip out also if you pull a little on them?

Sometimes they put ''below par'' pieces even when NIB. Make sure that your mag release goes far enough into the slot of the magazine where it get's hooked. It's the notch in the top of the mag. Compare the original with the other magazines to see the relative difference, could give you a hint on what to look for.

I've seen mag releases that get stuck halfway because of bad tolerences during their manufacture too so the magazine does'nt get hooked properly, this happens more often on amidextrous mag releases. Make sure it comes back properly everytime and goes far enough so that the mag notch will get hooked properly.

Do you understand what exactly is happening inside when you have that problem?

The well of the hop-up chamber is not going far enough into the magazine to push back the holding tab of the bb's inside the magazine well so the bb's do not fully get pushed all the way up to the nossle so in other words, your magazine is not getting hooked high enough in the magwell for the hop-up well to push down the tab holding back the bb's.

Your problem really feels like it's coming from your mag release.

Try to see if there is a way for you to tighten it more so that it clamps further in the notch of the magazine.
