does this sound good or bad?

So I've had this gun for 3 years now never opened it never done anything to the internals and I'm wondering if it sounds wank or decent cause I know it's not perfect cause it sounds loud any whiny but for me as someone who has no clue on what sounds to listen for I thought I'd just make this post just to see if any of you have any idea if its worth getting some work done on it. Just as a note it is a nuprol (please don't execute me) and it's been rather decent, it's the sopmod delta version)

it's a bit twangy but nothing horrible. at three years old a service with a reshim won't hurt.

It's defo a bit whiny but tbh no one will really care and I would personally keep it like that (partially because it's a nuprol). 

 

In all my years airsoft, the only gearbox that has failed me outright was a nuprol m4 gearbox. The teeth on the gears just exploded. And, other gearboxes did not fit into the gun without modification due to some metal tabs getting in the way. I remember they also have microswitches which also makes it non standard. By far the worst m4 I ever had.

I have the same model as that for a backup

 

sounds pretty much the same, I'm just gonna run it till it dies then gut it :D
