The LG400 also allows not only for the cocking lever to be mounted on the left or right hand side of the rifle but it can also be mounted to operate in a downward motion rather than having to lift it up, so instead of the lever getting closer to the scope during the cocking action is is actually getting further away from the scope as the rifle is cocked.

This is a major advantage that the older model LG300 does not have.

The Dominator is an LG300 and it needed the cocking lever to be redesigned to allow it to clear the scope and is why mounting a scope on an LG300 match rifle does not work without some (serious) modification to the cocking lever.
