Yankee Hill Machine Fat Cat 5.56mm QD Suppressor

Yankee Hill Machine Fat Cat 5.56mm Suppressor

The Fat Cat represents a refined approach to compact sound suppression for the modern rifle shooter. Built on decades of Yankee Hill Machine's reputation for quality and reliability, this suppressor combines intelligent engineering with proven materials science.

Design and Construction

The Fat Cat employs a new baffle geometry specifically engineered to reduce blowback—a critical consideration for shooters who value shooter comfort and firearm longevity. The suppressor is constructed from 17-4 phase stainless steel paired with a Cobalt 6 blast baffle, a combination that provides exceptional durability and thermal resistance. This material selection enables full-auto rating, making the Fat Cat suitable for demanding tactical applications and sustained-fire scenarios.

Performance Specifications

• Sound Suppression: 139dB at the muzzle
• Length: 4.25 inches (4.5 inches with sRx adapter installed)
• Diameter: 1.94 inches
• Weight: 11.2 ounces (13.2 ounces with adapter)
• Mount: sRx 1/2" x 28 quick-detach hub adapter
• Minimum Barrel Length: 10 inches for 5.56 NATO

What Sets It Apart

The Fat Cat's larger 1.94-inch diameter creates substantial internal volume, resulting in a lower, more pleasant acoustic signature compared to smaller suppressors. At just 4.5 inches with its included adapter, it's a full inch shorter than Yankee Hill Machine's Turbo K model, making it an excellent choice for short-barreled rifles and compact platforms where real estate is at a premium.

Included Components

Each Fat Cat comes equipped with:

• sRx 1/2" x 28 quick-detach adapter
• Mini sRx muzzle brake
• Your choice of standard or Cat's Ass end cap
