How to determine barrel twist

[DFBrews]

I have an upper/barrel that has no markings on it what so ever. I can tell the barrel is chrome lined which is a plus but I want to figure out what the twist rate is. Anyone have any ideas?

Take a cleaning rod and make a line straight down the length of it, and then measure how far you had to pull it through the barrel (with a brush on it) to get a full rotation of the rod. Hope that helps and good luck!

brilliantly simple it appears to be 1:9 thanks Nogaroheli

I told you that a week ago. Why don't you listen to me? It's because I'm man pretty isn't it?

I was looking for other options Nate and usually check out about 1/4 of the way thru most of your sentences.

No you are not man pretty... hairy and Irish yes.
