Upgraded Tokyo Marui m14. Internally: rhopped marui barrel, zci piston, shimmed Prometheus helical v7 gears, zci torque motor, guarder tappet plate, guarder sp130 spring, gate nano asr mosfet, cyma gearbox shell and selector parts. I’m forgetting what exactly it has for the compression parts. It does fire but the trigger trolley skips out of alignment when it does fire. Cycles well but needs new trigger contacts. The body was painted in the past and has had the paint stripped as well as possible. Is missing front sling mount. Will come with 3 midcap mags 3 hicap mags and optic. Check my bio for trades.
