I don't want to do the brush anodize removal trick and AW's deep tail caps don't look stock. Any cleaner solutions?
Neat/Clean ways of getting 2x18650 into a Mag 2C?

Just off the top of my head, I would think that with some creative bending (and maybe cutting) of the tailspring you could flip it upside down so that it still sits on the bare metal ledge while it would also center the 18650 and make contact with the negative end. I can't say that I've gone this route, but I'm sure it would take some trial and error to get it right.

I saw a Mag tailcap where the 'spring recess seat' of the tailcap was bored considerably deeper, so the stock spring seated much further down inside the tailcap. It looked very clean and nobody (well, non-CPF'ers) would know it wasn't stock.
I doubt that would give you all the depth you need, but perhaps it's a start.

Not enough length for 2x18650, that's why download had a Mag ring & 2x18650 kit, need to extend the mag a few mm to fit 2x18650 even without any spring.
The only way to fit 2x18650 & maintain the stock look is to shorten the bottom of the Mag switch, you can shave off a few mm, also shave the top & move the switch up by 2mm or so (Off center switch post but still clicks). I am not sure that's enough, might need to also thin the tail cap bottom from inside just a bit.

Theres GOT to be a way of mimicking the download's foam pad thing without the ring. The shorty tail spring mod, I've seen, but I can't remember who did it
If your 18650s are unprotected, or (maybe) very short protected ones, you can do the MagRing mod with no ring -- I ran a Mag61 this way for quite a while.
The ring is there to add the length needed for (most, if not all) protected 18650s and some unprotected, so without either boring the tailcap deeper or trimming the switch per ma_sha1's suggestion, not much to do...

Hmm, if I make a batt pack, I can use a plug and by pass the tail all together?
Start off by using one of AW's old C Cell extenders
Find them here
That will give you the additional length to use 2 x 18650 of any length
in a Mag 2C
I normally just strip the anodizng from the inside of the tailcap and
trim the spring to sit in the bottom of the tailcap.
I know you said you didnt want to do this but it is the easiest way
Other than that I suppose you could use the Mag Ring method but use a
spring instead of the rubber cushion

With downloads old kit, 2 unprotected 18650s will fit without the "ring" behind the tailcap.All you really need is a small piece of foam, some braided copper wire, a tube to hold the Batts, and a split ring a touch bigger than the inside diameter of the tailcap (please don't ask what size, I have no idea :shrug
. I put together one last week to run a 5cell 'numstar bulb.It's the size of the bottom end of a C-mag tail spring -- which is enough to know, since the easiest way to make one is to cut down a C-Mag tail spring.With downloads old kit, 2 unprotected 18650s will fit without the "ring" behind the tailcap.All you really need is a small piece of foam, some braided copper wire, a tube to hold the Batts, and a split ring a touch bigger than the inside diameter of the tailcap (please don't ask what size, I have no idea :shrug

Also take a look at a medium weight spring from a junker 2D light. I cut one down to fit into the original spring seat, then reshaped and filed the center coil flat so it sets inverted in the 2C tailcap. With a fitted PVC battery sleeve the 18650s make perfect contact w/ no rattle. It looks stock until it gets dark.....

2xUnprotected 18650 is a bit risky from safely angle.
When I do this type of mod I use a copper ring to extend the light body just a hair, and then sink the spring into the tail cap. I did not remove all the anodizing from the bottom, I just cut a groove around the very bottom edge of the tailcap so the spring would "snap" into the bottom and not fall out. 2x protected or unprotected fit in it. I also used a bit smaller spring out of cheap light that I had.
There are a couple of pics of what I mean in this sales thread.

I really like this solution except you need a lathe to make the plug that fits into the spring and the recess in the tailcap for the spring itself.
I have done it as simple as this, its neat and clean. Then you use a spacer to hold the batteries.
Not sure it will help but the batteries fit easy with this spring. Hardware store spring.
