Combat Application Technologies Dirty Dave RDM HUB 7.62mm Suppressor

CAT Dirty Dave RDM HUB, 7.62 NATO, 5.75 in., 19.6 oz, Inconel, DLC, SuppressorThe CAT Dirty Dave RDM is a Restricted Development Model edition from Combat Application Technologies. CAT describes its RDM editions as singular milestones in its engineering journey. They were born from a special advanced testing program, were never intended for broad release and will never be produced again. Each one comes from a strict, finite production run.This is the Dirty Dave RDM in the HUB configuration, a 7.62 NATO suppressor made from Inconel. It is 5.75 inches long, 1.60 inches in diameter and weighs 19.6 ounces.Built Heavier on PurposeRDM models are built with deliberately thickened walls and increased design parameters, which add 1 to 5 ounces of mass depending on the variant. CAT says this purposeful overbuilding raises thermal capacity, so RDM suppressors can endure extended firing schedules and extreme use without compromise.Proven CAT PerformanceThe RDM line delivers the predictable CAT performance its users know: high reduction of flash, sound, blast and toxic fume. The Dirty Dave uses CAT's Surge Bypass technology to manage gas flow and keep the shooter's experience clean.Optimized for the SIG MCX-SpearCAT optimized the Dirty Dave RDM for the 13-inch SIG MCX-Spear and a velocity of about 2,900 feet per second in 7.62 NATO. CAT lists a minimum barrel length of 13 inches for 7.62 NATO with the Inconel model.Inconel and DLCThe Dirty Dave RDM is made from Inconel, a nickel superalloy known for holding its strength at high temperatures, and finished in DLC. That pairing makes sense for a compact 7.62 suppressor that sees heavy use on short barrels.HUB ConfigurationThis Dirty Dave RDM is the HUB version, using the 1.375x24 HUB interface so you can choose the HUB-pattern mount that suits your rifle. CAT's spec lists no mount included.Care and UseLike any suppressor that sees hard use on short barrels, the Dirty Dave RDM gets hot. Give it time to cool between long strings of fire, check that your HUB mount is properly torqued before every range session and inspect the mount threads during routine cleaning.A Limited RunCAT released this strictly limited batch of RDM suppressors heading into 2026 as a thank-you to the community and a rare chance to own a piece of CAT history. Once they are gone, CAT says they will not be produced again.SpecificationsManufacturerCombat Application Technologies (CAT)ModelCAT/DD/RDM (Dirty Dave RDM)Part NumberCAT-DDHUB718-RDMUPC850059086490Caliber7.62 NATOLength5.75 in.Diameter1.60 in.Weight19.6 ozMaterialInconelFinishDLCTechnologySurge BypassOptimized Velocity2,900 ft/sOptimized Platform13 in.
