FW3A mod thread. Post yours!

lol is that “tactical” enough for them?

Kinda surprising nobody has melted a bottle cap onto the head of their light there yet if it’s popular.

Good day, does anyone know the o ring size used for the battery tube (switch end)? And the white oring too.Thank you

what is this??? how did you do this surface? very cool.

Looks like just sandblasted aluminum to me, I like it.

Big thanks to contractor

Very clever mod there :+1: how do you switch between the 2 modes? is it a custom firmware thing?

Firmware is flashed for use of secondary’s yes

Dbsar had a chalky white one iirc

does this work for the FWAA switch button, and which O ring size would you choose?

I haven’t checked the difference between those o-rings.

However, I can confirm that the space inside the button boot and the top of the switch in an FWAA appears the same as in the FW3A. I have a large bag of o-rings and every one of my FW3As and FWAAs has received the o-ring mod using the same o-rings.

Basically, any o-ring mod that works on an FW3A should also work on an FWAA.

thank you :slight_smile:

I assume the o-ring goes inside the base of the button?

The oring mod is quite simple:

  • Disassemble the tailcap
  • Remove the plastic nubbin from its socket on the inside of the rubber button boot.
  • Place the endcap on a table with the inside facing the ceiling.
  • Insert the metal button
  • Insert the rubber button boot
  • Insert the o-ring into the rubber button boot
  • Insert the switch PCB.
  • Insert and screw on the switch retaining ring.

Note that the FWAA has a small wide spring that sits around the outer edge of the button boot. It provides electrical contact even if the switch pcb is not snug. Make sure this is in position when reassembling. The FW3A does not have this spring.

the detailed steps is much appreciated

Im unable to turn the switch retaining ring in my FWAA, using a small flathead screwdriver

what do you use?

Im considering buying this snap ring tool, good idea or suggest other options?

I’ve always used the silver part of a binder clip.

thanks, got the ring loose with the tips of some needlenose pliers… need O ring next…

Yeah, that makes sense to me, given how the switch cover diameter is nearly the same (the FWAA is like 1~2mm shorter) . I’ve not yet bothered to take apart my switch. It works so well, I don’t mind doing a quad click for electronic lockout.

The MacGuyver in me just got a stiffy. Thanks! :laughing:

Btw, speaking of enlarged…
I put a fat o-ring at the base of the body tube on my FW3A, just under the clip ring. Wow, does this extend the easy handling of this tube light. So easy to hold & manipulate. That… didn’t come out right. :laughing:

aka Tactical Ring

also available for $16 from HDS…

Flipping the body, gives a similar grip advantage.

I think the idea of the tactical ring is that it makes it even easier to get a cigar grip, because the ring makes the ledge that stops your ring and middle finger even bigger.

Flipping the body tube would make the light harder to use with cigar grip I think. Doing so eliminates the ledge your fingers are supposed to grip.
