Seriously, based on the shape and size of the body I doubt there is a practical solutin. An M4, aka "Leopard Light" is pretty straightforward however, and would give output on either side of the MN20.
Thanks guys. I think the 1st solution is a bit spendy. I guess I could look for an M4 body and use the M6 head with an appropriate LA. The M6 would look so bad :devil: mounted to the AR though. And the mighty MN21 would be cool to try shooting with at night.
I'm considering my WE Rattlesnake EO-13 as well...
