hi all

i got my hands on a Surefire A21, LU60 collar and SW02 switch.

Now i have to choose the front assembly.

Considering that i want to run 1 cr123 battery, what do you suggest?

i've previously gone with a Defender head and an P60L bulb.

even if the bulb is made to work with 2 cells, it was good, but the defender head broke and ( and now i would like to pick something more lumen-performing, but still keeping the smashing capability.

i would like to get also one of those rubber finger ring but don't know which one will fit the A21.

please instruct me, since as you can see i don't have a much clear idea :p
