I forgot to add that it appears tweaked right after the front sight post.

Chop it off and use it for a pistol build

Do what colt does. whack the crap out of it with a lead babbit. Works for them.

This is actually one of the ways we were taught to straighten them in the Army. I usually told customers to come back later when I had to straighten barrels because they usually thought I was just bashing on their weapon for no reason. The look on people's faces always made me smile.

I have a Bushmaster M4 barrel and the front sight is also slightly canted. If I use the iron sights I have to tweak it all the way to the end to make it work. Are you using a scope or just the rear iron sights on the upper?

no optics, I traded the carryhandle/rearsight for a flip-up, has windage and elevation adjustments.

Your barrel is most likely not bent. I would put my money on canted front sight base. Somewhat typical on cheaper uppers.

Oh one of the reasons for owning a AK. If you had a AK I would just tell you to bend it back into shape. AR's I gonna tell you to buy or trade for a new one.

It sounds like a canted FSB. Are you getting consistent groups with your barrel? Have you also tried dropping an aluminum rod through the barrel to see if drops through?

Try the rod method, of if you have access to a lathe, take it out of the upper, chuck it up and spin it at a slow speed. You'll quickly be able to tell if it's bent.
If it's your FSB, hold the rifle in one hand and smack the fsb with a leather or rubber mallet, it will rotate a little bit, usually enough to fix the error.

It's easy to detect a bent barrel by simply taking a look down the bore. Clean the bore so it's nice and bright, break the AR down shotgun style and remove the bolt, then look down the bore at a bright light source. make the muzzle concentric with the chamber end while looking through it, and you should easily be able to tell if it's bent or not.

Im positive that the sights are dialed in. with my carbine I would shoot 2in groups in the bullseye at 25 yards, with the bushmaster all the groups were peppered about 3in AWAY from the bullseye from the 3oclock to 6oclock. thats only at 25yards.......

Just curious, how can your sights be dialed in if it's not shooting point of aim? Do you mean they are mechanically centered? If so, it's common for sights to need some adjustment from mechanical center to point of aim. Have you tried adjusting the sights to move poi to poa?

yeah the groups are pretty tight together, and yes the .22 cleaning rod and 30 cal rod didnt tell me anything :/

Just did, just like looking at it from the sids/up and down, if it is, its barely noticable

dont have access to one, but the rubber mallet is last resort..... but maybe only resort?

I hope so, better than the barrel. on cheap uppers It wouldnt suprise me, but bushmaster? :/
