Otis FG932 Brass Scraper Tool Set MSR/AR Multi-Caliber Cleaning Kit

The Otis FG932 Brass Scraper Tool Set delivers precision cleaning for MSR and AR-platform rifles across multiple calibers. This specialized kit removes carbon buildup and fouling from critical areas that standard cleaning tools cannot reach effectively.

What Makes This Different

Unlike generic cleaning kits that rely solely on brushes and patches, the FG932 combines brass scrapers with nylon bristles for targeted carbon removal. The brass construction provides the right hardness to scrape stubborn deposits without damaging receiver surfaces or bolt components. Each tool is sized specifically for AR-15/M4 and AR-10 platforms, ensuring proper fit in tight spaces around the bolt extension and chamber areas.

Key Features

• Brass scraper tools sized for AR-15/M4 and AR-10 bolt extensions
• Nylon bristle components for gentle cleaning of sensitive surfaces
• Multi-caliber compatibility covers 5.56/.223, .300 Blackout, and .308/7.62
• Precision-machined tools fit standard upper receiver dimensions
• Corrosion-resistant brass construction prevents scratching

• Compatible with Otis cleaning system components

The FG932 excels in high-volume shooting scenarios where carbon buildup becomes problematic. Competition shooters rely on these tools for match-day maintenance, while law enforcement armorers use them for thorough weapon inspections. The brass scrapers remove baked-on carbon from bolt faces and chamber extensions that accumulates during rapid-fire sequences. Temperature extremes and adverse conditions increase fouling rates, making proper scraping tools essential for maintaining reliability.
