Can you make a gen 8 JM M4A1 single fire in anyway?

Is there anyway you can make your JM M4A1 set to single fire?
Does the gen9 gearbox fit and is it that simple?

easiest way would probably install a gate warfet MOSFET as it allows you to program ROF and heaps of others

I used a Burst Avocado in the UMP. Similar to warfet program it for single or multiple burst per trigger pull.

a programmable mosfet however watch the size as there aint allot of room to play with so i use
one of these and use it for a larger 11.1 battery and room for a merf 3.2 and better battery connectors as well but you would need to make wiring come out the front of the M4
