This .750 low-profile aluminum gas block sits under a free-float or drop-in handguard on an AR-15 build. The low-profile shape clears the handguard while routing gas from the barrel port to the gas tube. Roll pins are included.
Features:
This block fits .750" barrel journals only; it will not fit .625" or .875" journals. Aluminum keeps the weight down but is less heat-durable than a steel block under sustained fire.
