Fett Affen’s BoreViper is a revolutionary product that cleans a bore more quickly than with the traditional method. With a single pull of the BoreViper , you will have a barrel that is clean and ready for action. Its incorporated bronze brush efficiently loosens hard fouling and lead, then the woven cotton floss that follows finishes with the final clean up. Completely washable so you can reuse it over and over. The Fett Affen BoreViper has 155 times more cleaning area than a standard patch, making for a cleaner bore in less time. The brass-weight on the end of the cord is imprinted with the bore size and slips easily down the barrel. The BoreViper has no exposed metal to damage the rifling or crown of your barrel. The Fett Affen BoreViper is an excellent product to use at home, at the range or in hunting camp.
