C.A.T. RDM Alley Cat 556 HUB

The Restricted Development Model (RDM) editions are not just C.A.T. RDM Alley Cat 556 HUB suppressors; they are singular milestones in CAT’s engineering journey. Born from a special advanced testing program, these RDM units were never intended for broad release and will never be produced again. Each one represents a strict, finite production run, a true one-off opportunity. Built with deliberately thickened walls and increased design parameters, RDM models carry an added mass of 1-5 oz depending on variant.

This purposeful overbuilding raises thermal capacity, allowing them to endure extended firing schedules and extreme use without compromise. Unlike unknown new entrants to the suppressor market, the RDM line delivers the proven and predictable CAT performance. You already know, love, and trust – the high reduction of flash, sound, blast, and toxic fume. As we move toward January 1, 2026, CAT has chosen to release this strictly limited batch with unique, one time pricing to empower distributors, dealers, and customers alike.

It is both a thank you to the community and a rare chance to secure a piece of CAT history – an offering as uncompromising, exclusive, and enduring as the operators it was designed to serve.

ALLEY CAT represents a dedicated suppressor range designed for law enforcement, government, and military departments. ALLEY models are developed by C.A.T’s own team, composed of current and former Special Mission Unit personnel, who bring decades of tactical and operational expertise.

ALLEYCAT models emphasize reliability, low breach fume, reduced sound signature, minimal blast propagation, enhanced durability and unmatched form factor output to meet the rigorous demands of high risk tactical operations. With end-user focused design, ALLEYCAT is tailored to support the critical missions of specialized units across various branches of service. Visit Beaverdick Defense
