I get this on a 14.5 middy that runs 100% suppressed. Gassed lean without the can, but slightly overgassed with the can. So weird. Not a big enough problem to where I've researched it because it's an ACOG setup shot mostly prone/longer distances.
One thing I had happen before is excessive spring tension on the bolt catch.... either due to the detent hole being shallow, or a spring too long.
