Default m&p15. identify barrel.

Hello.

I'm trying to identify the barrel twist rate and if the barrel is a 223 or 5.56.

This is on an M&P15. This is the lower: (normally it should say the caliber on the lower right under "M&P 15" right?



...and then both sides of the barrel. There is no identifying marks on the bottom of the barrel. I haven't removed the rail to see if there are any marks under the barrel there. (are they normally in that location?)





Thanks guys!
