I got this idea from a thread I saw over on AR15.com. I could never figure out why Ruger mated a stainless steel barrel with a painted black aluminum receiver. I never liked this combo, so I did some poking around and found the info to turn my rifle into a shiny machine! Here's the whole thing all put together: The next couple photos show the receiver in close-up. I disassembled the rifle completely, then took the receiver and drenched it metal stripper that I got from the auto parts store. Just a word of caution, you don't want to get that crap on you. Anyway, after about 30 minutes the paint just sloughed right off. A little scrubbing with a brass brush here & there to get the nooks & crannies and I was good to go. I then started wet sanding the receiver, first with 300 grit, then 600, then 1200. Last was a rubdown with 0000 steel wool. After the sanding regimen, I mounted my orbital buffer in a vise, spread some Mother's Aluminum polish on the bonnet and began buffing the receiver. I managed to get a pretty nice shine on it that matched my new bull barrel pretty well! I also sanded and polished the bolt, and did a little sanding on the inside of the receiver to knock down a few rough spots. All that's left to do now is take it out and sight it in! I might be able to some time next week. Here's hoping the weather cooperates!
