I had the chokes opened on a shotgun with chrome lined barrels.
I did not like the finished look inside the barrels.

I have no complaint about the constrictions or performance of the chokes.

Just the micro finish after the chrome was machined out.

I don't know if Orlen polishes reamed barrels to mirror bright or not.

But I did not like the residual scratches in that set of barrels, and promptly sold it.
I should have specified a micro finish, and I didn't.
Live and learn.

Out there doing it best I can.
