As the fet mod was insufficient for American Milsim I had to create a physical block to the Auto selector on the rifle.
I managed to get the Auto disabled by adding a drop of JB Weld to the top edge at the end of the selector connecting rod. This prevents the selector cam from fully rotating and engaging the Auto setting. The fix is not permanent in that the JB Weld can be filed down to restore the Auto functionality if I ever have to sell the weapon.
Case resolved for now. Hopefully Pesto will be able to put his thinking cap on to come up with a resolution to the potential of a semi-lockup occurrence that can be done easily in the field.
As it stands now, if the semi-lock occurs, I will have to open up the battery compartment and temporarily unplug the MERF and plug the battery into the motor directly. This isn't ideal given the PITA factor involved with the 6 small hex screws and the potential occurrence of this scenario in the midst of a firefight.
