Bore Tech's Gun Cleaning Muzzle Guards are an essential tool for properly cleaning firearms from the muzzle. Shielding the barrel's crown from accuracy affecting damage caused by rod drag or rod strike, our Muzzle Guards simply and effectively provide the necessary protection. Made from barrel safe brass, our muzzle guards center the cleaning rod in the barrel and prevent the cleaning rod from dragging or striking the crown during cleaning. Simply slide the guard onto the cleaning rod before your brush, jag, mop, etc. and you are ready to safely clean your firearm from the muzzle.Features:Shields the barrel's crown from accuracy affecting damageMade from barrel safe brassPrevents the cleaning rod from dragging or striking the crownEasy Use
