The MSR/AR Maintenance Tool Set contains the tools to clean some of the most critical parts of your firearm. Included in this set is a scraper, locking lug scraper, straight pick, pin punch, nylon end brush, a compact receiver brush, and two rod handles. These tools will not scratch the firearm, and with them you can now thoroughly clean areas such as the locking lugs, the slides, bolt face, rails, and any other hard to reach places.
