Liberty Lubricants TriboStars 5.56 Chamber

Liberty-Tuff™ TriboStars™ 5.56 AR Type Chamber Locking Lug Cleaning Pads come infused with Tribo-Solve™ Synthetic Solvent, to help dissolve and carry away the carbon and crud that builds up in the locking lug recesses of your AR-type firearm's barrel extension.

Simply "thread" a TriboStar™ to the end of a .223/5.56 bore brush(or threaded jag) until secure, insert into the locking lug recesses and rotate clockwise to remove gunk that was broken loose by your chamber brush.
