Gearbox Window

There are two common forms of the Version 2 gearbox. The first type features a window towards the rear of the gearbox, with the spring visible. This is found in all Armalites that use the Version 2 gearbox, as the window allows the body tabs of the receiver to pass over the raised portion of the gearbox. The second type of Version 2 gearbox lacks this window, and is generally found on non-Armalites. While the windowed style of the Version 2 can be used in non-Armalites, the non-windowed version cannot be used in Armalites due to the lack of space for the body tabs to pass over the gearbox.

[edit] Known Issues with V2 Gearbox

* Non-reinforced Version 2 Gearboxes cracking under extreme pressure from a high rated primary spring.
* Anti-Reversal latch sticking
* Higher chance of motor misalignment, as it is not mounted to the gearbox (as in other versions), and so not as precise.
* Unreliable semi-automatic fire (gives bursts of automatic fire).
