Each Modify Hybrid Barrel features a stainless steel base for a secure hop-up mount and a set of barrel grooves and two size o-rings which function as a barrel spacer. This model fits most carbine size AEGs with a mock suppressor.
The 407mm Modify Hybrid Barrel is constructed of both stainless steel and high strength aluminum. The base of the barrel is stainless steel, and features multiple hop-up cuts to accommodate all types of hop-up units, including the TM M14. In addition, the included Modify Hop-Up Bucking has 3 internal ribs that match the grooves on the barrel, providing a tight, air-proof seal. The 407mm barrel is ideal for most carbine size rifles. It provides a slight extension on length over a standard M4 barrel, and will fit some other rifles such as a KM4A1.
