Tuning Excessive wear on Airforce barrel

[Huntersglen]

Lother W .22 x 18" has uneven wear from the o-rings. All wear is on underneath bottom side at rear end. And top side in the middle. None on either of the sides. Looks suspect as bushings are not round when checked with a gauge or maybe thin breech is bent. I am going to sell it as is and point out the uneven wear marks.

These pictures aren’t clear focus so it’s really difficult to tell. I do think it’s pretty normal to get some of the finish worn away because of the way the breech action works.
