Echo 1 Complete 6mm Gear Box for Mk5. I bought this for parts tbh but its stock parts like i expected. not shimmed or greased well at all.
Pros:
came with a fuse
Spring guide is solid steel (good ig)
Says the spring is 400+fps so
Gearbox shell
Solid bushings (not ball bearings but can be a pro/con)
back wired
you didnt spend your money on this
Cons:
Gear grease seemed like this thing sat in a box for a couple years
Shimming sucked like expected
Got better gears from my crossman duty calls M4 (had better parts than this)
Bevel gear had a 1cm wide,3-4 cm long,and 1-2mm deep scratch that looks like someone took a dremel to it.
Air nozzle is trash (looks like the one that came in my first aeg plastic gearbox crossman rifle)
Spring guide does not have the ability for a M4 buffer tube screw to screw into it (its one solid piece of steel)
Screw set is a hex screw set so you need a hex key set
