OGcigs Republic 14500 mod

[suspectK]

... well, based on the fact neither the supplier nor ogcigs has sent me response emails to my questions...I won't buy anything from them, but I got this little mod on a trade... (not worth the $70 asking price btw...)

What is the diameter of this mod? Hopefully I can get an answer before I justify buying calipers just to find this out.

Thanks
