CAT Kitty Kat 5.56 Compact 718 Inconel Suppressor

The CAT Kitty Kat (KK) is purpose-built for shooters who need maximum maneuverability without sacrificing real suppression performance. As CAT’s shortest dedicated 5.56mm suppressor, the KK is engineered from rugged 718 Inconel, delivering exceptional durability, heat resistance, and signature reduction in a footprint designed for close-quarters movement, vehicle work, and compact rifle setups.

Despite its minimal length, the KK provides the advanced suppression, blast mitigation, and flash reduction CAT is known for—refined specifically for 5.56 NATO systems. Leveraging CAT’s Surge Bypass technology, the KK efficiently manages gas flow to reduce back pressure, maintain reliability on short carbines, and control muzzle signature even during rapid strings of fire.

Optimized around the 14.5" M4 Carbine, this suppressor shines in duty-oriented and tactical environments where speed, mobility, and system balance matter just as much as raw decibel performance. Paired with the included AI NANO 1/2×28 QD mount, the KK locks in with consistency and rapid detach capability, making it an ideal fit for shooters running semi-auto 5.56 platforms who demand uncompromising performance in the smallest possible package.
