Gun cleaning is simple so let’s not over complicated it
There’s nothing wrong with having lots of gun cleaning supplies if you need it and you can definitely mess up a firearm by using the wrong tools. In all honesty, I have many gun cleaning brushes and tools that I have absolutely no idea how or what to use them for. I picked up some of the Otis gun cleaning kits and at first found them a little frustrating to use because I could get the same grip on the wire as I could with a cleaning rod. I realize there are compact advantages to using this system and for any military or long hunting trip they makes sense.
Some scraping tools are necessary for cleaning out the chamber of your AR15 because that gun is hands down the biggest pain in the ass to keep clean although sometimes people over clean them. I like to have a atleast one Hoppes boresnakes for all of my rifles because when I get my rare range time in, it’s not fun to have to spend more than about an hour to clean my guns and I’m of the type that needs to clean them after every time I take them out. I have used break free clp for most of the time but for long term storage of firearms that aren’t going to get used for 6 months or more I am using the M-Pro7 gun oil because it seems to stay on better.
