Can flash hiders work a muzzle brakes?
The most effective flash-hider on the market for an AR15/M16/M4 is the Vortex. Second is the Phantom. Characteristic of these flash-hider designs are long longitudinal slots. Muzzle brakes or “compensators” work on the principle of harnessing the high-velocity gas exiting the muzzle to: (1) negate the rearward movement of the rifle and (2) redirect some gas in directions to compensate for the natural muzzle movement from firing. For the former (#1), the “brake” effect comes by having those high-velocity gases put pressure on surfaces which are normal to (“at a right angle to “) the bore axis. As the gas hits those surfaces, it “pulls” the barrel forward, opposite the direction of recoil. For the latter (#2), there are typically small holes drilled in the top and maybe on side of the comp for a “jet” effect” to counter-act the natural muzzle rise and to-the-strong-side movement. Since the primary design feature allowing a brake/comp to work is a system of one or multiple surfaces normal
