Raw Aluminum AR-15 .750 Gas Block w/ MMC Armory Logo and Top Picatinny Rail
The Gas Block on your AR-15 / AR-10 style rifle is an integral part of the gas system that allows your rifle to cycle. By tapping off-gas from the barrel and diverting it back into the gas key of the bolt carrier group, there is enough inertial force to unlock the bolt carrier, send it rearward to the recoil assembly, and extract and pickup another cartridge to fire. PIC-BLOCKS have a Picatinny rail machined into the top of the main body, allowing for sights and other Picatinny accessories to be mounted. However, gas blocks tend to get extremely hot during use, and attaching polymer accessories or sights is not recommended.
