Flash hider vs muzzle brake vs compensator

Short answer: A flash hider cuts visible flash. A brake vents gas sideways to cut recoil and is loud to your sides. A compensator vents up to fight muzzle rise. Match thread and caliber before blast pattern.

Flash hider (A2 birdcage, 3-prong, SOCOM-style): reduces flash you see at night. Mild blast. The common 5.56 default.
Muzzle brake: side ports push gas out and back to reduce rearward recoil. It is the loudest for people next to you on the line.
Compensator: ports mostly on top to hold the muzzle down for faster follow-ups. Pistol comps like the True Precision Cobra do the same job on a handgun.
Hybrids mix flash reduction and ports. Many suppressor-mount devices are hiders or brakes that also accept a can.

Thread comes first. Most 5.56 AR barrels are 1/2x28. Most .308/AR-10 barrels are 5/8x24. AK devices are often M14x1 left-hand. The device's bore must suit the caliber. A 5.56 device on a .30 caliber barrel is a bullet-strike risk. Titles list thread and caliber. Brakes and comps must be timed so the ports face the right way: shims, crush washer, or jam nut.
