5.56 - .223 Bore Guide - Sinclair
If you have a stainless barrel you REALLY NEED to use a bore guide or rod guide as some call them. The bore guide prevents the cleaning rod from scratching the inside of the bore as the rod goes through the barrel. This is the Sinclair version for the AR15 5.56/.223 caliber.
