AR15-pattern rifles and carbines perform best with proper cleaning and maintenance, and Otis Technology is a leading source of portable service kits for those, and many other, firearm platforms. The MSR/AR Cleaning System is a comprehensive kit that, in addition to more generic cleaning supplies, includes AR-specific brushes, scrapers and tools for servicing areas and components like the “star” chamber and bolt carrier group. The system even includes the Golden Bullseye Award winning B.O.N.E. tool, all in a small, zippered carrying case.

Watch this week’s NRA Gun Gear of the Week video as Joe Kurtenbach breaks down the kit and demonstrates its utility by cleaning a couple critical components on an AR-pattern rifle.
