I have an RRA with a Predator Pursuit upper, s/s match barrel, etc. On my XD and Sig pistols, to clean their barrels, I first run a bore brush through them a few times, then a mop with Hoppes #9 through it, wet an old tooth brush with the same Hoppes and scrub the breach and anywhere else carbon is built up. I then let the barrel soak in the Hoppes while I clean the rest of the firearm and mags. Then I will wipe the outside of the barrel down, and run a bore snake through it several times, then spray the barrel down with a light coating of Rem oil, and reassemble. I have a chamber brush for the AR, and plan on getting a solid rod, something that wont damage the crown (like a Dewey rod?) for using my .22 bore brush, and following my same pistol process for the AR barrel. Anyone see any problems with this? I dont like using the patches anymore since I started using the bore snakes.
