The PATRIOT Series by Otis offers the essential firearm maintenance gear to properly clean from Breech-to-Muzzle. Each cleaning kit is designed to clean one caliber or gauge and features a new tool that acts as both a T-handle and a driver for the included 4 bits. Made in the USA and at a price that won't break the bank, you can pick one up for every firearm that you own. Available in 8 configurations.
