Ok so this is my first and only rifle, I'm new to the game. The book and Ruger says no copper brushes down the barrel. What do you do to clean your sr556?
As the great Jack Benny used to say, "well....."marxman, First of all, you posted this thread in the wrong forum. It should be in the Maintenance Forum .... not the Semi-Auto forum. As soon as I finish this post, I will move it for you.
The next issue is ... no where in the Ruger instruction manual does it say NOT to use a copper brush. Fact is, bore brushes aren't copper anyway .... they are bronze. The cleaning instructions say to use a bore brush wetted with solvent.
That a far cry from your first post but is still way off the chart. If you take everyone's suggestions literally, you would never buy a gun .... but if you did, you would never shoot it, and if you did, you would never use anything harsher than a soft piece of jersey T shirt to clean it. Fact is .... bronze bore brushes have been used for about a century and so far, there is nothing to suggest they do any damage to a bore. Let's not be making mountains out of molehills!,the guy was saying only use a bore brush if necessary
