Today i finished the M4 modernisation, the body was bored for 18.. accu family compatible.
The boring was not through the whole body, i left 1 mm of original diameter from the head side for prevent to loosing contact from minus lamp to minus body. It is possible to load Accumulators only from the tail cap side.
Now the flashlight can use MN21 MN20 lamps from M6 with two 18650
and it can use the original Surefire M4 Devastator lamp - MN61 with 3 18350 combined with metal spacer instead the 4-th accu.
MN20 lamp 250 lumen inside
Thanks)
