Gunsmithing NP3 Plating on a BCG

Re: NP3 Plating on a BCG

I had 10 bolt carriers plated with Nickel Boron Nitride a couple years ago. Sold 7 of them and have 3 left, i'd forgot about them untill I saw this post. They are stripped M16 carriers.

I've been holding onto them in hopes of finding bolts and carrier keys to finish them, thats looking less likely these days.

No reason to sand them... just send them in. They strip and coat them. I've got two I had done. Works great!
