How do you tell if your gearbox is a virgin?
How do you tell your AEG mechbox/gearbox is a virgin, meaning like no one tampered with it or replaced it?
Just wanted to know, when I bring my gun for an upgrade I wanna take a look at it and see if has it been tampered with before, just wanted to know how do you tell.
Any positive/useful information would be greatly appreciated!
Thanks!
