This Micro Gas Block from Midwest Industries (brand part no. MI-MGB-625) is a .625-inch diameter, low-profile gas block finished in black. The gas block sits over the barrel’s gas port and redirects propellant gas into the gas tube to cycle the action; a low-profile design keeps a clean, snag-free line under a free-float handguard instead of protruding above it.
