Wolfpack Armory Romulus 556 5.56mm Suppressor - Black Built for hard use, the Wolfpack Armory Romulus 556 combines Inconel 718 construction, a low-backpressure Radial Flow design, and HUB-compatible mounting in a full-auto-rated 5.56mm suppressor. The Romulus 556 measures 6 inches long and 1.61 inches in diameter. It weighs 14.2 ounces without the mounting adapter and features a black C Series Cerakote finish. Each suppressor comes with a Low Profile Plan B adapter and a 1/2x28 Night Howler Comp. Radial Flow Design The Romulus 556 uses Wolfpack Armory's Radial Flow design to cool and direct gas forward at a controlled rate. The design is intended to produce very low backpressure while reducing flash and sound. Lower backpressure can help reduce the amount of gas directed back toward the shooter. Wolfpack designed the Romulus to work with many factory rifle configurations without additional tuning, although performance can vary by firearm and setup. Inconel 718 Construction Constructed from Inconel 718, the Romulus 556 is designed for demanding firing schedules and is rated for full-auto use. Its durable construction makes it an option for shooters looking for a suppressor suited to hard-use 5.56mm rifles and pistols. Wolfpack lists no minimum barrel-length restriction when the suppressor is paired with the Night Howler Comp or a similar brake- or compensator-style muzzle device. Consult the product documentation for the requirements applicable to your configuration. HUB-Compatible Mounting The Romulus 556 features a 1.375x24 HUB-threaded rear interface, giving shooters the option to use compatible HUB mounting adapters. This model comes with Wolfpack Armory's Low Profile Plan B adapter and a 1/2x28 Night Howler Comp. The included components give customers a matched mounting setup while retaining the flexibility of the HUB interface.
