After spending a week at training for work, I decided it would be a good way to decompress by refinishing my M3 on Friday. After taking the gun apart and cleaning everything then roughing the surfaces (sand paper scuffing) I heated the parts with a hand held torch then applied a high temp oven/stove paint to them. After allowing the paint to dry I went back over them with the torch again to help cure the paint. I left the parts sit over night then after assembly I took a 0000 steel wool and went back over the gun to knock off the shine. I am happy with the way it turned out (though there is one spot I might touch up) As I shoot and handle the M3 it will develop the appropriate wear and handling marks. The only thing I did not do was try to straighten my rear sight as it appears to have been dropped or impacted at some point in the guns life. It has a small "flat" on the top now instead of being fully round but the thing shoots POA/POI so I'm not messing with it.
If you look back at my previous posts you will also see that I added the magazine "loop" back to the gun, making it look better than those with which the "loop" has been cut and ground off. Now with the refinish, the "loop" and adding an oiler and sling, my M3 should be back to the specs that the British have considered to be field ready.
