Every AR that's gas-operated and doesn't use a piston system needs a gas block of some type to cycle between shots. If you're building one of those awesome old-school or retro style ARs, yours may have a fixed front sight or some folding variant that doubles as the gas block. But if it's any number of countless newer designs, it'll most likely have a gas block that only serves as the gas block. And more often than not, its design will be low-profile in size, so that some type of handguard can fit around it to shield it. The handguard will a pic rail on top on which you'll then mount either a fixed or a folding sight to serve as the rifle's front sight. If you're in the latter group, this is your gas block. See below for more info.
