Re: Duracoat question
Yes you can duracoat the bolt.
My experience is that as long as you have enough tolerance between the bolt and raceways you will have no problems.
I think there is a time limit to apply duracoat over a previous coat, but I am not sure. At any rate it is best to blast with aluminum oxide first so if I was going to re-coat a rifle I would do that to remove the old coating. anyway.
Do some searches and there is a lot of info on Duracoat on the web. I tried my hand at it this winter and have been very pleased with the results. One piece of advice, think very carefully about how you will hold each part both while spraying and while it is drying.
