AR-15 A2 Rear Sight Re-Align?

[Ironbarr]

My new (last September) AR-15 16" detachable carry handle required a barrel refit due sight alignment - rear sight was almost in the left stops without nearing zero. Two months later I got it back from MFR with a stainless barrel - but now the rear sight is far right (laser zeroed).

The question: Would there be any sense in resetting the eye piece along the travel screw in some procedure in order to compensate for whatever this problem is? AND, if it's doable, what procedural steps would be necessary and what tools are advised (seems the large headed side screw doesn't budge)?

Thanks,

-Andy

You might want to try'r first. From my little bit of experience with laser zeroing (or any gizmo zeroing for that matter), I've found that it leaves alot to be desired. Most of the time, it won't even hit a 2'x2' target at 50yd.

Shoot, report back. You're dismissed.

YT...

I think jollies are fun too... especially when the jolly-ee is so much younger than the jolly-or. Your turn in the barrel.

Thanks, though.

sometimes the front sight base is slightly canted
the result is usually a far left zero

one fix is a kawallop with a no-mar hammer
