i think we all know blueing is a chemical reaction by now.its very poor at protecting a guns finish.parkerizing is a step up.home brew cold blueing cant get deep enough to last on a gun.have you every popped a set of your rings off to see what rust and crud lives under? i highly doubt if youve exposed steel lapping rings and cold blued those rings after even a day or2 of hunting in rain there would be rust issues unless well oiled and cared for. i dont oil anything but bores. i have my guns tefloned being i gun hunt some 2 months out of the year . cheapo aluminum rings on an aluminum scope body is gonna conform somehow i guess. :rock:

Sure, I change out out and sell and buy scopes all the time. Never seen or heard of the problems you are worrying about. Neither has my gunsmith. You sure all this stuff has happened to you? Or are you just going by hearsay?

Never saw a ring that was rusted where it contacted the scope and i've removed a few hundred scopes. i've had people bring me a couple dozen rifles that had the scopes ruined from mis-aligned rings. Prior to lapping, i check the scope rings very carefully with the alignment bars: If the rings are going to require a lot of lapping they go back to the vendor.

Am not a gunsmith but i do scope a lot of rifles and sight them in. i will not install a scope without first lapping the rings.
