I noticed this for sale and it came PW on a few uppers chambered for 5.56
https://www.primaryarms.com/dead-air-armament-556-muzzle-brake-suppressor-mount-1-2x28 Looks like a .30 cal bore. With such a large bore does this basically become a flash hider unsuppressed at that point? It should have less blast and concussion. For those in less than free states would this be a good alternative to a flash hider?  |

as an over bore brake it will be fine
If you mount a 30 cal can on it, It will not be as quiet as a dedicated 556 suppressor, but it should drop the dBs reasonably with subsonic loads |

Typical allowance for exit port of a brake is .020" give or take, so you would not get the recoil mitigation of proper sized exit port, being over 10x larger. For use inside a can I don't think there will be much difference in report, provided the can is 5.56
All brakes are loud, the larger port isn't going to help much with that. |

They work fine. There’s a tiny performance loss that most people won’t realize. I think MDT just did a video on oversized brakes.
