My trusty Kwa MP7 I've had for almost 5 years, still runs strong as ever even though In last parts replacement I wanted to try some things and now it chronos around 530 with .25s. not cqb friendly but fun to mess with, or just swap valves to bring it back down Internals are standard but with angel customs loading nozzle and cnc rocket valve, DP enhanced piston head, and a falcon inc. 6.03mm inner barrel and 60 degree bucking. (barrel length is 363mm for those who care) Does have the the old Kwa flaw of the shell cracking on the right hand side at the take down pins which happened within 6 months of ownership, haven't had any issues and just a cosmetic blemish imo. Thanks for checking my listing and lmk if interested :)
