    AR-15 shooting right

    I have a built AR-15 pistol with 7.5 inch barrel that is shooting 12 inches right. It groups fine and with sights fully adjusted it still is 12 inches to the right. Any ideas?

    What Sight/sights are you using? What distance are you zeroing at?

    If it's a pinned front sight or gas block, you need to whap the **** out of it with a rubber mallet to rotate the block against the pins. True story.

    Make sure your sights are adjusted in the correct direction.
    The more you sweat in training the less you bleed in battle.

    I have tried 2 different sets of sights both flip up. Shooting at 50 yards. The rear sight is maxed out to the left and the group is 12 inches to the right.

    Free float barrel with low pro gas block. Flip up front and rear sight. Groups good just 12 inches to the right with the rear sight mechanically maxed out to the left. I've heard that the crown may be the issue idk.

    If the front sight is on the hand guard the hand guard could be on crooked or the barrel nut is bad. Front sight on the barrel the uppers bore to face could be off sight not installed perpendicular or the barrel is bad.

    Picks and more info would help.

    I'm going to remove barrel and inspect then reassemble on another upper to eliminate mounting fitment issues. I feel it is either barrel crown, upper to barrel nut fitment, or bad barrel. I've only shot it at 50yds. It does group but is off right as stated. Also may try another barrel on existing upper. I have options just all involve some sweat equity. Thanks for all the replies.

    Or is that to rotate the bbl and front sight together, at the bbl extension?

    Put it on a hard chair (protect the chair though), sit on the thing and run a wooden dowel through FSB and give it a pop.

    Good quality sights? Got others you can try??

    What type of handguards? Sounds like the FS is mounted on the HGs? Are you SURE you installed the HGs straight? break out some straight edges and squares.

    I had a sh***y set of HGs once that mounted so sloppily with hand pressure I could move the zero around many inches....
