So, a month ago I shot a full auto AR with a ciener kit installed. The rails were smoother than glass. There was little to no resistance when charging (other than the spring of course), and cycling was flawless. So my question. How can I make my rails that smooth? My guess is a polishing wheel, some jewellers rouge, and a lot of patience. If anyone has a good step by step guide or would post a tool/product list with some instructions I think it would help quite a few people out. Thanks |
Take the JAC kit apart and grab your dremel and polish. here ya go home.netcom.com/~uzisubgun/id3.html |
I used 600 grit paper to knock down the rough parkerizing and then polished with a dremel and brass compound as suggested in the link above. It worked like a charm. I think I've posted this here before, but here it is again...this is part of a post from Subguns.com by Eric at Lakeside Machine. Where to polish:

| I did mine with sandpaper on top of a steel plate ( glass works too) and worked it in a random pattern. Started w/ 400 then 600 then 800 and finished at 1200 grit. I feel that this method polishes well yet keeps the rails flat & true. Polishing the feed ramp helps alot, don't overlook that step. As for the guide rod after thousands of rounds mine has marks in it from the spring so I don't think it's polish job lasted very long. Granted most of those rounds were FA and that might make some difference in accelerating the wear. |
