I know alot of people like to mate the barrel and upper but what Im told AA mates the barrel and upper perfectly aligned, flat top of upper and bore match horz. I to very new to this AR thing but can attest that mine was. Fired it first time last week and scope was set 0 up/down and 0 left to right first 2 shots where 1/2 left and centered up/down, took two more after adjustment and dead on . still needs more work at 100 plus yards but did not have much time that day. love my first AR, Lower is a PSA but I think if you ask Mark nice he will still help you with the group buy price on a bare lower???
