L119 Gearbox Issues

[brewer17]

Right guys and gals,

I built myself a L119 a few months ago from the G&P reciever and a Classic Army gearbox. When im selecting semi or full auto it is really stiff. Since then Iv been doing some research about it and it turns out that CA gearboxes have a size issue with the reciever so thats whats causing the stiffness.

Unfortunatly it does not say which other gearboxes fit and which dont. I got a spare Chinasoft gearbox that fits perfectly but Id like something a little more reliable.

So my question is, which fit and which dont? Below is a link to what I was looking at getting.

Iv been looking at the Guarder enhanced Version 2
