What is the most common twist in factory made AR barrels? I have a DPMS,ATI and a Bushmaster in 223 and a R 15 in 204 which I know is 1x12. Just curious what the 223's are. Is there an easy way to find out?
Thanks....

ss bbl common is 1/8

tight fitting patch with a cleaning rod that turns freely in its handle. start the patch at the throat, mark the rod at the back of the receiver,mark the TOP of the rod, and the top of the handle.right next to each other,...now push till the rod rotates one full turn(mark on top of rod lines up with mark on top of handle)...mark rod at back of receiver again....the distance between the two marks on the rod is the twist...do it a gain to make sure...

On an AR, the barrel manufacturer will engrave the caliber and the twist on the barrel, usually near the muzzle
