Flash hiders/muzzle devices affect on accuracy?

+1 on the VG6 Gamma here. It's my goto MD.

My two guidelines are

1) Don't cheap it i.e., pay more for a better assurance of machining quality.
2) Lightly torque it and use Rocksett or similar.

Anyone had any experience with the EC Tuner Brake?

V6 Gamma (.300 BO version) is what I like to run. As to accuracy effect - sometimes. On an M1D sniper rifle, the cool 3 prong flash hider hurts accuracy. On a 5.56, it rarely really matters that much. On a .300Win Mag, I bet it does, hence tunable BOSS. In 6.5 Grendel, I can't say. It's a mild round so less whip than many.
