SCAR owners, a touch of help, if you would.

Post by fooschnickens » 16 Dec 2009, 22:28

Small backstory. A good friend of mine is coming back from active duty for good in a few months. As a welcome home/attaboy gift, his parents are getting him a SCAR (lucky, right?). His dad knows that I know a bit about FNs and tapped me to spearhead this operation. Basically, he wants to do one of three things to the rifle to commemorate the occasion: engrave it, dye it black, or both.

The engraving shouldn't be too difficult with the rifle stripped. What he (and myself) is wondering is if the upper metal portion (shown below in color) can be pretty much made bare so that it can be coated to complete the black look. In looking at some of the field stripped photos of the rifle there doesn't appear to me much else to the upper once the barrel/piston assembly is removed other than the accessory rails and rear sight.

He's fine with the dyeing process, the man's a whiz when it comes to models and if it's plastic/polymer he's likely made it a different color. :laugh: Depending on how well it turns out I'll probably have him do mine as well once I get it.

So, lay upon me thine wisdom and I will share the process for those who can't wait or want to pay for a black SCAR.

Well looky what I found on gunbroker...

This REALLY makes me hope the upper receiver is easy to take apart. I found a couple videos detailing the field stripping and barrel changing process and looks like the only caveat will be removing the gas piston system if it's required by the coating company. If anyone is willing to take a gander in there and snap some pics I'd be much appreciative. :thumb:

How much is cost a factor?

I believe, stressing on the believe part, that these guys can strip anodizing, and re anodize a new color without screwing with tolerances.

I don't think duracoat is a good fit in that situation, if re anodizing is out of the question then something like ceramakote or KG gun kote would be better, anything ceramic and bake-on.

If you want to be really one of a kind get all the internals and the gasblock finished with Ionbond.

Stripping anodized material off is pretty aggressive. It's really no different from stripping paint off a car or varnish off a table. I'd be worried about the acids eating away at something inside and causing it to not function properly. At least I have found that the gas system is not actually housed in the receiver itself, but is part of the barrel assembly and can be easily removed. I've sent out a few emails to companies that offer duracoat, cerakote and teflon-s services to see what their opinion (and price) is on the matter. At the very worst we'll have to ship the rifle to them to see if the coating it will muck up any operation. Since most of the motion is inside the upper receiver, an external coating would likely not interfere with very much since the receiver can be masked off to have the material applied in specific areas (ie the outside). IIRC the only external moving part is the charging handle.

Things are coming together. Just waiting on replies now. :)

Small update for you gents.

I've heard back from several companies offering cerakote and duracoat services and it looks like the average charge to coat just the upper cover is $85. The highest was $125 and the lowest was $50. It's roughly the same surface area as an AR flat-top upper so most places quoted me the same price for that service.

I made sure to tell them it was anodized and that wasn't an issue as most places used an oxide blasting to get down to the bare metal before coating anyways.

If all goes according to plan for me tomorrow I'll be the proud owner of one of these puppies and shouldn't need much more help in terms of info. Then I can get started on blackening my own. :cool:

When I start that I'll make a build thread detailing the whole process from start to finish for you guys.
