About The Modification

Been using this procedure with worn-out sector gears with success. Actually my TM (Tokyo marui) M14 uses a sector gear with this modification and has seen its fair share of use and abuse regularly for more than a year without encountering any problem. Will post some updates about the condition of the reinforced sector gear when I open up the gearbox/mechbox for its routine lubrication and maintenance. With the introduction of low priced infinite torque ratio gear sets. This airsoft modification has been considered unnecessary, though I still found it really useful for TM (Tokyo marui) version 7 gearbox/mechbox and found the fabrication of a smaller version 7 spur gear to meash with the infinite torque ratio gears a bit of an impossibility…. Thus rendering this modification a requirement for airsoft guns (particularly the TM M14) using the version 7 gearbox/mechbox for SP/M150 rated spring applications. In order to achieve the desired and required power rating (FPS) for a marksman/sniper airsoft rifle and still get a decent (if not reliable) lifespan out of the gear set.
