Just a short note,it doesn,t take anything to make or clean a gun on the outside for cosemtic effect. The gunsmith you took the gun too should have explained to you about the proceedure he would have to go throught to replace this part!!! That was his responsibililty to you as a customer,then explain if you wanted to have it cleaned while it was apart for him to do so or not.I personally would at least clean it up a little without charge,for if i didn,t then something else happened a customer would have come back if somthing went wrong and they would say well you just did this ect. and make me look bad. This way he would cover his butt,make the custjomer happy and all would be well,no problems in the future. But a lot of customers take for granted taht a smlith will clean there gun when its apart,wrong.We are not in the business to do work for free!!So it was a wrong set of communicataion on both of your parts. Like you don,t take your car in and say to the mechnic change my oil,and when you get your car home and check it in a week it is dirty? why is that you said change my oil,you didn,t say with new oil,he just put oil oil back in it,from some other car. or enen your own old oil. Plus some "gunsmiths" put oil on them if they have blueing tanks in ther shop to keep the guns there safer from rusting from the fumes from the blueing tanks in the air rust the guns. i doon,t know i wasn,t there,but just something to think about. vangunsmith
