I have a 5″ 13.5×1 LH 9mm ADCO barrel and it is just amazing! I have it mounted on an AR along with a Surefire Ryder 9 Ti suppressor. It shoots 3″-4″ groups @ 100 yds. just shooting from my elbows resting on my bench using a SPARC red dot for the sight, If you are looking to build a 9mm AR, give serious thought the these barrels.
