Can't help you with accuracy pics...or really with a good accuracy report as I've only run my dissy with A2 irons or a red dot. That barrel really is a pig though. I had mine profiled down to .635 behind the gas block and it made it so much lighter. The one I built for my father in law is still stock and it's a beast. Also, both of our barrels run brass ammo perfect, but won't cycle steel cased. I opened up my gas port a bit on mine. Didn't seem to alter feel or function but I haven't had a chance to run steel through it yet. Ive read the newer DTI barrels have a bigger gas port than when I bought mine
