Ok I am up to the point of mounting my Rainier Match barrel onto a BCM upper and had a question about coating the barrel...The barrel came bead blasted stainless...Im looking to make the barrel look like milspec phosphate..any suggestions...Ive heard Hitemp engine paint..duracoat..cerakote...what say my AR gurus?

Cerakote sniper gray looks a LOT like Parkerizing (zinc rather than manganese), which is what is on a mil-spec barrel. Hi temp engine paint is not quite as good a match, and is less durable and resistant to solvents. but without something to compare to, you probably won't notice. IF you are paying someone to do it, duracoat and cerakote will cost about the same, go with cerakote.

I would think cerekote would be the most durable.

Thx guys...would spraying itself be something you recommend i try myself or send it out...I guess duracoat would be the only one I can spray without special equipment
