I used Chads barrel on a 7.5" Ar 556/223 cal with a BTM adjustable gas block. After 45 secs on single firing to adjust the gas block this little sucker ate all the ammo I threw at it. Crap steel cased 223, federal 556. Barrel is very good and was very cheap (bought it back in Jan). Ill be buying my next one off him for sure as Im currently building another 7.5 pistol.
