The reason there are so many Ruger upgrades is because they're necessary.
I have a friend who cleans his bore with copper disolver stuff, and the runs a wire brush through the bore, multiple times..... every time he shoots...... is he gonna kill the rifleing in the barrel? I personally clean my gun bore with rem oil once in the spring, and once after hunting season is over, and have never used copper-whatever the crap is.... my gun drives tacks and has for 23 years. Just curious???
FWIW, On some of those copper cleaners in sez right in the directions to NOT use a wire brush. Plastic brush is ok.
