anyone have a link to rail diameters?

[tmckay2]

im debating on a free float rail system but i don't want one that is really bulky. i was wondering if there is a place to compare troy, larue, dd, etc. i know most of yhm are the thick ones, i want something that doesn't strain the hand so much. thanks

I just build 2 using the TROY TRX series. More cost effective than many and quite narrow.

Here is some info on rails:
