This brass 300mm long and 6.03mm internal diameter high precision inner barrel fits MK23 (T.Marui fixed slide). While this 300mm length barrel provides best performance and shooting power in the MK23 (T.Marui fixed slide), the suppressor/silencer efficiency is reduced to remaining about 20% only. Heavy BB (i.e. 0.3g or heavier) is recommended to increase the shooting accuracy and range.
For easy and stabile installation, our CNC 6063 aluminium outer barrel (#3054) is highly recommended to be used together with this long inner barrel.
All products are made for airsoft only. They are not made for real steel firearms.
