Description
Complete Full metal gearbox to suit M4/M16
Features
- 8mm bushings
- ball bearing spring guide
- rear wired
- 370-410fps
- Stock CYMA Long type motor (with neo magnets)
- Full auto capable
Could also be used as a base for a build, as the shell itself is quite good with the right cut outs and fully TM spec
I have personally opened one of these gearbox’s, air sealing is not 100%, this can simply be improved and was able to get 420fps by just tweaking the compression parts,
