i got an A1 complete upper to make a retro build but instead i would like to blacken the upper to match a new frame i know that some one has finished one in here how did it work ans what product did you use thanks todd |
This is an old A1 upper, and a new DPMS lower. The discoloration around the windage knob is Breakfree which I used for assembly. As you can see, the upper perfectly matches the lower's factory finish. I sprayed the upper with Norrell's Molyresin, www.molyresin.com. I used the "Flat Black Socom", now simply called Flat Black on the Molyresin site, which is a perfect match to most lowers on the market now. Do a search and you can find Stickman's thread on using this product. I found these, just too easy. Mine came out perfect the first time: www.coloradoshooting.org/ar_refinishing.htm and www.black-rifles.com/forums/index.php?showtopic=477 I used a bucket of cheap lacquer thinner as a degreaser, just soaked the upper in there overnight. A Badger airbrush, which I used for HO railroad modeling, and I had everything I needed. I used the Molyresin straight from the bottle, no thinner. For cleanup, cheap lacquer thinner. I get the stuff in the blue and orange gallon cans at Wallyworld. I preheated in the oven, set on 170*F. You do not want to get grease from the rack on your receiver... I set the receiver on a cookie sheet covered with clean foil. I am used to airbrushing, so no problem. But say the worst happens and you have a big nasty run? NOT A PROBLEM. Until Molyresin is oven cured it can still be cleaned off. Dunk it back in that gallon of cheap lacquer thinner and let it soak a bit, scrub it off clean with a brush. Let it dry, back in the oven to warm it up, and respray. Until it is baked, one hour at 300*F, it will not have full hardness even if it feels dry to the touch. After baking it is very hard and difficult to scratch. It is as durable as the original anodized finish. It goes on very thin, will not fill in markings or machine marks. The part simply looks a different color.  That is the Grayish Black Molyresin. You can also go the other way, REALLY retro, and spray the upper AND lower in the old Colt gray color. For the old M16's from the 60's color use Gray Flat Molyresin. That is approximately the same color (within minor batch to batch variation) as the gray dry lube finish on USGI magazines. |

Howdy Folks I used the Brownells Gun-Kote Matte Black on my 1903 Springfield and it turned out very nice. I just followed the directions on the can and turned out great. Product # is #083-051-001. I don't know how to post a picture or I would have. You bake the part in the oven at 300 to max of 325 for 1 hour. It looks like it was parkerized when complete and is resistant to all gun cleaning chemicals. MC |
