Watch this video put out by MadBull Airsoft... "The officially licensed Noveske outer barrels are modeled after Noveske’s own line of stainless steel barrels that are highly regarded by shooters for their high quality constructions and polygonal rifling.  The original Noveske Rifleworks stainless steel barrels have a bead blasted finish and bull barrel design.

With lengths starting from the 7.5in Diplomat to the 18in SPR barrel, the Madbull Airsoft fully licensed Noveske Rifleworks barrels are great additions to your custom airsoft collection.
