How to remove a screw that has been punched?

[alpalwal]

I recently got a m44 barreled receiver and I want to remove the bayonet from it because it won't work with the muzzle break I have. It turns out that the reason I have been having such an issue unscrewing it is because someone punched the bottom of the screw in 2 places.



Any good ideas on how to get the screw off?

Anyway you can drill out the screw?

[alpalwal]

I probably could. It looks like it'll be a pain but that might be what needs to happen

[Spiggy]

lightly apply centerdrill or dremel cutting wheel, it will remove the peened metal and allow you to unscrew it

[bohoki]

just unscrew it it not welded with kryptonite its just little peens toughen up

have you ever met russian peened screws?

they're mithril or something! you will need to bonk out the peens or it won't budge
