The Systema PTW M16 Barrel comes complete with a steel outer barrel, tight bore 6.04mm inner barrel, and hop up unit. This is an upgrade for owners of the generation 1 PTW. The early versions of the PTW were designed for military and law enforcement training, thus they were made with 6.1mm inner barrels so the user could reuse BB without having jams. The newest generation PTW is designed for airsofters who only use clean BBs, therefore it already comes with this 6.04mm.
This product is for the Systema PTW only, it is not compatible with any other type of airsoft gun.
