.223 Wylde heavy barrel, 1/8 twist, target crown, .980"/.900" diameter, uses .936" gas block (included). 20" length. Shoots ~.8" groups at 100yds with 55 gr handloads, about 1.25" with everything else, great barrel, I'm just wanting something lighter with a faster twist. I can meet in the Mesa/AJ/Gilbert area most afternoons. I also get over to the west side every couple weeks. Not interested in anything other than cash offers. If the posting is up it's still available no need to ask.
