Lots of M14 parts. I'm guessing they are cyma m14 given the receiver is a cyma.

Included is:

Gearbox shell

Gearbox (probably complete but I've not been inside to check) 

Motor cage and motor 

Front end with it on sight

Some bits that go one the outside of the gearbox

Upper receiver 

Selector switch 

Trigger guard with locking mechanism

A few little springs that you need for gearbox assembly as well. 

It's a bit of a random selection I know but it may be useful to someone. 

£18 posted for everything. 

Give me a shout if you want more detail on any of the bits here.
