I read Stickman's how to thread, had an airbrush (and I know how to use it!), and ordered some Norrell's OD and black. I had heard of Norrell's Moly Resin for about 20 years, and it had a great reputation. I had just gotten a Cavalry Arms OD lower, and had parts to build the upper, and decided to go all the way. Great finish the first time.
Norrell's can be purchased online at
www.molyresin.com.
The Norrell's OD is a perfect match with Armalite and Cavalry Arms OD furniture.
This one had a black upper and gray lower, now a perfect match:
Here is another I did:
And I couldn't stop myself, here's one with a Cavalry Arms OD lower:
The color really does match well, but the texture of the surface is different, and the metal parts with Moly Resin reflects the flash more:
(Edited to add: Do you see the flaw? Look directly above the C in the Cavalry Arms name on the lower. That tiny ding. This flattop upper and the other flattoop at the top with the Armalite furniture were both purhased from LAR as "blemished". I finally figured out that little ding was the blemish. The anodizing was black and even, and it was hard to see before coating, even now, only because of the flash. The other receiver with the green furniture at the top of this post, I never did find the blemish.)
I've been doing the flash hiders black because they will get black stains anyway.
Go on and order some flat black, too. I did the front sight post, flash hiders, and a few other parts in black. The ones above with the DPMS "Mangonel" flip up rear sight now have Eotech 512's on them. I plan to disassemble the flip up, do the aperture part in black, the rest in OD.
To stretch the OD, and use more of the black, I've been doing the barrel nuts, delta snap ring and spring, and barrel portion under the handguard in black, as well as the flash hider and front sight post. Only the handguard cap, front sight base, and forward portion of the barrel were done in OD. I did the black first, bake it, then masked off the flash hider, and sprayed the OD.
On some of the uppers I've done, I did the forward assist in OD, another in black. It's kind of cool with the OD and parts black mixed.
I don't think any of these coatings will stick to DPMS receivers, or Mega, which are teflon coated.
