last BB stuck in mag

[mirinjawbro]

Hello all

have a GBB m4a1 that using both mags the last BB stays in the mag so the gun never "locks back".

any ideas to get the last bb to feed?

thanks

What make is your replica?

Does it happen with all of your mags?

I previously had encountered the same issue with my GHK M4, turned out is was the Devil Hunter feedlips, that were by his own admission when I contacted Pablo

They we’re ever so slightly out of spec, and stopped the follower reaching the top

You should maybe stretch the follower spring a little to see if that helps, or shim it at the bottom to add a little more compression

Some folk put a bb in below the spring to do that

It'll reduce your ammo count by one bb, but should make the difference

Failing that, you could bend the tab downwards on the replica, the one that the magazine will lift if applicable as I don’t know what M4 platform your are pewing

happens on all mags. 

gun is a WE M4A1 GBB

so the spring has more tension. good idea

ill give it a go thanks
