G&g mgcr mag

[Gunner91]

 just picked up the g&g mgcr gbb. Having feed issues with the one mag supplied. Anybody know how to fix this? The mag when the bolt is retracted has a bit of play in it. When the bolt is in battery the mag is solid, so when you fire and it retracts the mag drops a mil or two. Can provide a video if needed

Try shimming the inside of the magwell, it's common to use the fuzzy side of velcro
