Exigent Defense StreetGoblin556 5.56 NATO Inconel Suppressor + BattleHawk Armory Direct Thread Mount The Exigent Defense StreetGoblin556 is a compact, hard-use 5.56 NATO suppressor engineered around 3D-printed Inconel 718 construction, low-back-pressure performance, and a short 5-inch overall length. This package also includes a BattleHawk Armory 1/2x28 HUB Direct Thread Suppressor Mount, giving shooters with compatible 1/2x28 barrels a straightforward mounting solution right out of the package. Built for SBRs, AR-15s, and demanding suppressed rifle applications, the StreetGoblin556 combines advanced additive manufacturing with a proprietary gas-management system designed to control sound, flash, and blowback without adding unnecessary length to the host firearm. 3D-Printed Inconel 718 Construction The StreetGoblin556 is manufactured from Inconel 718 using Direct Metal Laser Sintering (DMLS). Its monolithic, tubeless construction eliminates traditional stacked baffles and welded seams while allowing Exigent Defense to incorporate complex internal geometry that would be difficult or impossible to produce through conventional machining. Inconel 718 provides excellent resistance to extreme heat, erosion, oxidation, and repeated firing schedules, making the StreetGoblin556 well suited to high-round-count rifles and hard-use applications. Low-Back-Pressure Gas Management At the heart of the StreetGoblin556 is a proprietary coaxial forward-venting system. Expanding gases are redirected through an annular pathway surrounding the bore, helping reduce the amount of gas driven back through the firearm. For suppressed AR platforms, reduced back pressure can mean less gas directed toward the shooter and reduced disruption to the host rifle's operating system. The design is particularly attractive for shorter-barreled 5.56 rifles where compact overall length and gas management are priorities. Integral Flash-Reduction System An integral four-prong counter-rotation internal flash hider works alongside the suppressor's internal flow geometry to reduce visible flash signature while contributing to its overall sound-management system. Despite its compact dimensions, the StreetGoblin556 measures only 5.0 inches long, weighs 13.1 ounces, and is rated at approximately 32 dB of sound reduction. HUB Compatible The StreetGoblin556 uses the popular 1.375x24 HUB/Bravo mounting interface, providing compatibility with a broad selection of HUB-pattern mounting systems. This package includes the BattleHawk Armory 1/2x28 Direct Thread HUB Mount, providing a simple direct-thread option for compatible 1/2x28 barrels. The BattleHawk Armory mount is precision machined from 4140 steel and finished in black nitride for increased wear and corrosion resistance. The mount threads directly into the suppressor's HUB interface and provides a secure connection to compatible 1/2x28 muzzle threads. Graphite Black Cerakote Finish The StreetGoblin556 is finished in CERAKOTE C-Series C-102 Graphite Black, providing a subdued appearance along with additional protection against heat cycling, abrasion, and environmental exposure.
