Help me choose a compensator for my Grendel....

[Drifter]

Saw a brake advertised with holes coming out the front, supposed to be quiet, do not recall where.

BRT offers a Covert Comp:

And Troy offers the Claymore Brake:

But neither is currently produced to fit typical 9/16-24 Grendel muzzle threads.
