Alpha C-1 rings

[October_V]

I have the Trustfire Alpha C-1, 2672 at DX.
I'd like to put GITD rings in the head.
They look like 24mm, but thought I should ask before I buy.

Can anybody confirm or correct my thoughts?

Thanks.

It should be 26-27mm, but those silicone o-rings (including GITD) are stretchy enough that a 24mm o-ring will fit in there.

I was thinking of putting them inside the head, on top of the glass lens. But stretching some around the outside would look great too. I guess I could use most of the 10 pack.
