Otis FG368HT 7.62mm Chamber Brush AR Platform 8-32 Thread Bronze

The Otis FG368HT chamber brush eliminates carbon buildup and fouling from 7.62mm AR platform chambers with precision-engineered bronze and steel bristles. This specialized cleaning tool reaches areas standard brushes cannot access, ensuring consistent chambering and reliable extraction.

What Makes This Different

Unlike generic chamber brushes, the FG368HT features dual-material bristle construction combining bronze for carbon removal with steel for stubborn fouling. The 8-32 thread pitch matches Otis cleaning rods perfectly, while the 1-inch bristle length provides optimal contact with chamber walls. Standard brushes often miss critical areas where carbon accumulates most heavily.

Key Features

• Dual bronze and steel bristle construction removes carbon and metal fouling effectively
• 8-32 thread pitch ensures secure attachment to Otis cleaning systems
• 1-inch bristle length reaches full chamber dimensions in 7.62mm platforms
• Compatible with AR-10, SR-25, and similar .308/7.62x51 rifles
• Precision-wound bristles maintain shape through repeated cleaning cycles
• Corrosion-resistant materials withstand solvent exposure
• Compact design stores easily in range bags and cleaning kits

Chamber fouling causes extraction failures and accuracy degradation in high-volume shooting scenarios. The FG368HT addresses this critical maintenance requirement for competitive shooters, law enforcement armorers, and precision rifle enthusiasts. Bronze bristles scrub away powder residue while steel elements tackle copper and lead deposits that accumulate during extended firing sessions.
