Black River MFG Benelli M4 Ported Barrel

Upgrade your Benelli with Black River MFG's 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. Their 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. Black River MFG's are drilled from 4140 to ensure the highest quality possible. All of their barrels come with their extended ported choke which is threaded in Benelli Mobil thread pattern.Specifications: Color: Black/FDE/Grey/OD Green (Cerakote) Length: 18.5" Brand: Black River Manufacturing Choke Thread: Benelli Mobil Gauge: 12 Gauge Material: 4140 Steel Models Fit: Benelli M4, Benelli M104 Shell Length: 2 3/4" and 3" Lining: Chrome Lined What's Included: Black Benelli M4 barrel Ported extended choke #5 Please NOTE: This product is made in Turke
