Depends. How good of a shot are you? Open sights Ive done about 1.5" at 100 meters on a lead sled. Im running an XCR-M, keymod, lightweight. 200 meters with iron sights I was about 2.5" I think. Toss an optic on anything and you can dial that down. Just like any gun, its more the shooter than the tool. Id bet the thing is sub moa capable for a good shooter. Ammo i was running was hornady .308 superformance, forget the gr. Some day i plan to toss on an Elcan Spectre (1.4x-6x flip I think they are), with the .308 reticle.
