I have the same problem hard to explain but I figure it out is to change a new long ejector and the problem goes away. (hence my old ejector has no damage).

Yes 24 twist

My open gun didn't like it, schuemann barrel 9mm major, no matter I've tried shoots everywhere. My open gun likes acme bullet shoots accurate.

I have both IPSC Alex cmore mount and thumb rest and they used hex 6-40 screws. thanks;Ron

Try racking the gun without the installed extractor. Thanks:Ron

bump fire? possible

Take out the upper receiver. Insert an empty magazine and wiggle it up and down (observe the movement with and without pushing the release magazine). If the magazine is too loose, that will create problems with feeding ammo because the magazine is too low (eventually resulting in a nose dive). This usually occurs when using a plastic grip 2011. Thanks!

Glad you made it.. Happy shoot!!
