Polished Mag Tube
Posted: Thu Mar 10, 2022 12:50 pm
The mag tube on my Frontier was so rough that when I would wipe it down the patch would leave small tuffs of cotton stuck on the tube. The grooves were holding dirt and under the hand guard there was surface rust in the grooves even though six months ago I had wiped it down with CLP.
I started out with 320 grit sandpaper to take the grind marks out of the tube, it took quite a while to get the tube smooth. i followed up with 400, 600,800 and 1000 grit sandpaper. It took less time to work from the 320 grit to the 1000 grit than it took to remove the original marks with 320.
At first the oxpho blue was not covering the tube evenly so I started heating it in front of my propane heater then wiping it on tell the tube was cool. I did one third at time overlapping the application, then lightly polishing with 0000 steel wool and cleaning with alcohol. I had to repeat this process four time to get the desired effect.
I think it turned out good, definitely matches the barrel better.
