Will 2 168s pilas operate an M4, I've read that a 9p with an a19 extender will work with these batteries, and since in this configuration you essentialy have a 4 lithium configuration as the M4, this should work?
Two Pila 168s fit great in the M4 with the spring from JS Burlys, but you will need to use the 9volt lamps: N2, MN15, MN16 instead of the 12volt M4 lamps.
l agree, leukos nailed it. If you want to use the M4 lamps you need 2 A19's
and 3 Pila 168s to power M4 lamps. I use that combo alot but I have been warned by many that putting 3 168s together is not a good idea. I have not had a problem. If you use the 9-volt lamps N2 is my pick I do not mount it on a weapon.
