Engineered for compact suppression on 5.56 platforms. The Fat Cat uses revised baffle geometry to reduce blowback and maximize usable internal volume for a lower, more manageable tone. Rugged construction and a full-auto rating make it suitable for demanding duty and rapid-deployment scenarios.

Key Specifications

• Caliber: 5.56 NATO — optimized for 5.56 platforms.
