Take the RB-17 Challenge

Apply RB-17 Gun Cleaner to your bore brush and pass it 6 or 7 times through the bore of any barrel that has already been cleaned with any other gun cleaner. The RB-17 Gun Cleaner is a gel and will stick to your brush smoothly without dripping or wasting. Leave RB-17 Gun Cleaner in the bore for 6 or 7 minutes, then scrub the bore again with RB-17 Gun Cleaner making 6 or 7 more passes. Now wipe out the bore with a clean patch. The gray looking residue you will see is lead, copper fouling, powder residue or rust coming out of the lands and grooves of what you thought was a clean bore. The lands and grooves in the barrel are what gives the bullet its spin. Competition benchrest shooters have long recognized that a clean barrel is absolutely essential to achieving fine accuracy. So, if it is accuracy you want, RB-17 Gun Cleaner is the product you can trust. After cleaning, apply RB-17 Finishing Oil with a clean patch for protection. Always oil your gun after any cleaning.
