I'm hoping someone can help me.

I recently bought some replacement barrels and found a lip approximately 3/4 the way down the bore.

Firstly, I  can't see any reason for this damage. I checked the pistons that came with it and can't find any damage to them.

Secondly, would it cause any problems with the running of the engine. I'm not sure if the rings go that far down for them to be affected by it.IMG_20180821_171835.thumb.jpg.cfbd5063bc6c01bd457d3f2745978ae6.jpg

Possibly pistons placed in barrel to keep right piston with right cylinder, pushed past normal stroke ht. and some damp has got in and caused a bit or corrosion? If it is below the 'normal' wear line, a light hone should take it off.
