A new and improved design recoil unit for the TM M4 Recoil Shock series has been undergoing beta testing for a couple of weeks. Photos below are sneak preview of our tech installing it. This unit is heavier and we recommend that it should only be used for upgraded gearboxes.




This new design is specifically engineered toward keeping the gearbox free from the stress and vibration of the heavier recoil unit. Testing this myself, I was surprised at how heavy the recoil is, your shoulder would sore if you use this for a whole day in the field.
Out test also showed no problem on a standard Tokyo Marui gearbox after repeated full auto firing day in and out. Out surprise came when the magazine catch broke in two, and then the bolt catch paddle broke afterwards.



After repeated testing, I guess the die cast parts of Tokyo Marui can’t take the vibrations and the abuse the heavier recoil unit produces. And again, surprisingly the gearbox showed no sign of breaking, no cracks whatsoever.



When this comes out, again we highly recommend upgrading your internals as well as parts that would not be able to stand the extreme vibrations of this unit, like the magazine catch and bolt catch paddle.
Watch for it, coming soon.
