Details: This is a fully CNC precision machined P90 Gearbox Shell from Retro ARMS. This shell has an integrated motor cage and has been completely redesigned. This Gearbox cannot be used to replace the Thompson V6 Gearbox.
As with all Retro products, Please keep in mind that Retro doesn't recommend springs over M150 to be used with this Gearbox, Although Retro doesn't recommend using springs over M150 strength, I'm sure this Gearbox is capable of handling springs stronger than that.
