The Maple Leaf KWA KRISS Vector 6.01mm Barrel and EVOII Hop Up set is a complete tightbore inner barrel assembly for the KWA or KSC KRISS Vector SMG gas blowback airsoft gun. This precision barrel comes with the EVO II Hop Up Unit and Bucking pre-installed, which delivers upgraded range and accuracy.  This barrel is the extended version of which effectively doubles the length of the inner barrel and is designed to be used with a silencer that covers the additional barrel length.  Use of this inner barrel will result in an increase in velocity, depending on the type of gas that you use.
