Description
The Griffin Armament HUB HRT-556™ AM is an ultra-low backpressure 5.56mm suppressor built for hard use while maintaining high levels of sound and flash reduction. Its additive-manufactured Nickel 625X™ superalloy core provides a durable foundation for the suppressor, while the HUB-compatible design allows users to configure the system with compatible mounting interfaces.
The industry-standard 1.375×24 TPI HUB thread provides broad mounting flexibility with compatible Griffin Armament HUB adapters or other manufacturer inserts. The printed core is laser-welded to a machined rear for warranty serviceability, while the high-performance flash hider end cap contributes to sound and flash reduction. The ultra-low backpressure design is intended to benefit both right- and left-handed shooters, with minimal point-of-impact shift.
