This weapons maintenance system provides you the necessary tools to completely break down and clean some of the most critical parts of your firearm. The Memory-Flex cleaning rods, solid brass slotted tips, 100% cotton cleaning patches, bore brushes, and an all-in-one cleaner, lubricant, and preservative allow you to quickly clean the receiver, chamber, neck and bore. Also with these components, you can easily strip the copper, carbon and other residue from in the barrel. The brass obstruction removers are used to knock out bore obstructions and stuck cases. The components from the brass scraper tool set are specifically designed to clean the hard to reach areas of your firearm. The brass scraper helps to clean carbon deposits from flat surfaces such as the bolt face and rails. The handy picks are engineered to clean the locking lugs, while the pin punch can be used to remove pins from any firearm held together with a pin system. The end brush is used to remove carbon and to lubricate the slides. The male and female rod handles can attach to any of the brass scraper components to increase their length. Everything is neatly packed in an 11oz., pocket size softpack case.
