Hi. I just placed a SilencerCo Omega 36M into jail.

I have a few questions.

When using the suppressor, is there any difference between using a flash hider vs a muzzle brake?

When using the suppressor, is there any reason not to just buy a 30 caliber brake and use that for 5.56 as well?

Other than the not included muzzle device, is there anything else i will need to mount the Omega 36M to my rifles?

When mounting the muzzle devices, are any sort of thread lockers advised?

Thanks in advance!
