Exigent Defense StreetGoblin556(TM) 5.56 Suppressor The StreetGoblin556(TM) is a compact, hard-use suppressor engineered to disrupt expectations-delivering serious sound suppression, reduced gas blowback, and extreme durability in a package built to compete far above its price point. Designed for SBR and duty-grade AR-15 platforms, the StreetGoblin556(TM) blends advanced materials, aggressive internal geometry, and forward-thinking gas management to create a suppressor that punches well above its size class. Constructed entirely from Inconel 718 and manufactured using Direct Metal Laser Sintering (DMLS) additive manufacturing, the StreetGoblin556(TM) features a monolithic, tubeless design with no welded seams or stacked baffles. This one-piece construction allows for complex internal structures that cannot be achieved through traditional machining-resulting in enhanced sound attenuation, improved gas flow control, and exceptional structural strength under sustained fire. At the core of the StreetGoblin556(TM) is a proprietary coaxial forward-venting system that redirects expanding gases into an annular vent path surrounding the bore. This architecture significantly reduces back pressure, minimizes gas blowback to the shooter, and improves weapon reliability-especially important on short-barreled rifles and suppressed gas-operated systems. The result is a flatter-shooting, cleaner, and more controllable rifle, even during rapid strings or full-auto fire. An integral four-prong counter-rotation internal flash hider further enhances performance by disrupting sound waves and dramatically reducing visible flash signature. Combined with optimized frequency manipulation and internal flow paths, the StreetGoblin556(TM) delivers impressive suppression and flash reduction from a suppressor measuring just 5.0 inches in length. With a heat tolerance exceeding 1,400AdegF, Inconel 718 provides outstanding resistance to thermal deformation, oxidation, and erosion. This makes the StreetGoblin556(TM) exceptionally well suited for high-round-count training, duty use, and harsh operational environments including maritime, desert, and high-humidity conditions. The suppressor is finished in CERAKOTEA(R) C-Series C-102 Graphite Black, offering a durable, non-reflective coating that resists abrasion, heat cycling, and environmental wear while maintaining a low-visibility tactical profile. Featuring industry-standard 1.375A-24 HUB (Bravo) threads with wrench flats, the StreetGoblin556(TM) supports a wide range of direct-thread and quick-detach mounting solutions-allowing shooters to tailor mounting options to their mission or host rifle. Compact, brutal, and unapologetically effective, the StreetGoblin556(TM) is built for shooters who want maximum durability and real-world performance without excess size or weight. Available at BattleHawk Armory. Direct thread adapter sold separately.
