The HUB HRT-556™ AM Silencer is a highly durable ultra low backpressure 5.56mm HUB-compatible suppressor constructed from Griffin’s proprietary Nickel 625X™ powder alloy utilizing state-of-the-art SLM additive manufacturing technology. This iteration of the HRT-556 Silencer shifts priorities to deliver an ultra low backpressure unit optimized for hard use while offering high levels of sound and flash reduction performance. Left handed shooters will benefit from the very low backpressure system as well as right handed shooters.

These silencers utilize the industry-standard HUB threaded rear (1.375×24 TPI) allowing the end user to configure their suppressor with any of Griffin’s HUB mount adapters or other manufacturer’s inserts.

The proprietary patent-pending Nickel 625X™ superalloy showed in testing a ~68% increase in yield and tensile strength over additively manufactured INCONEL® 625 at 1200°F.  INCONEL® 625 is a commonly used suppressor alloy in current next generation military suppressors.  Additively manufactured Nickel 625X™ is stronger at 1472°F than INCONEL® 625 cold formed sheet material at room temperature.  INCONEL® 625 cold formed material provided adequate service in the last several decades of military suppressors.
