Black River Benelli M4 12 Gauge Ported Barrel BLACK

Benelli M4 ported barrel Upgrade your Benelli with our M4 ported barrel. When the cartridge is fired, gases push the shot down the barrel and as it passes each port some gas is vented out to counteract muzzle rise and reduce felt recoil. Our barrels are drilled from 4140 steel instead of 4130 which has nickel in it which makes it softer. 4130 is used because it can be extruded to make barrels to cut down on costs leaving you with a low quality barrel. Ours are drilled from 4140 to ensure the highest quality possible. All of our barrels come with our extended ported choke which is threaded in Benelli Mobil thread pattern.
