I plan no getteing the bolt carrier coated at aome point but also want to do the pistons. Making them easyer to clean and more durable.

StrangerDanger Posted January 3, 2018 Share Posted January 3, 2018 How thick of a plating is it? When I had Nickel Boron applied to a set of pistons, it increased their diameter and I was forced to fit them to the barrel assembly. My experience with NP3+ on the pistons has been better. I guess they're thinner of a surface finish. Quote Link to comment Share on other sites More sharing options...
Drinktothat421 Posted January 3, 2018 Author Share Posted January 3, 2018 TiNi is vpd not like nickle boron plating. It is 1 - 2 microns thick. I know adding a coating could just make it not work. Haha Quote Link to comment Share on other sites More sharing options...
