Do that and let us know. The fore end has some give in the screws so you can slide it forward or backwards to fine tune the mag fit. Pushed forward lets it hand free and rattle around, pushed back against the mag keeps it tight and firm. I tend to go looser and deal witha slight rattle than have to grab a pinched mag to pull it out.
If none of that works you may have to take the action out and actually adjust the "bottom metal" trigger guard part which has a similar sort of give set up dependng on how you tighten it up but Ive never had to mess with that, Ive only messed with it in taking everything apart and fiddling, not actually diagnosing an issue with it so Im not so familiar with how it effects things.
