Big bore AR's are very difficult to master, shooting a bolt rifle is easy in comparison. No offense at all OP, are you sure it ain't the nut behind the bolt? Also like others said.. you don't exactly have a top tier barrel on there and that's the most important component for accuracy in gas guns next to ammo.
BTW It would serve you well to post your questions in this matter on the snipershide semi auto section. The mod of that forum, padom, is quite knowledgeble on this stuff and should be able to help you for sure..
