Griffin Armament Printed Nickel 625X HUB HRT-5K AM Suppressor .22 Cal (5.56mm) 4.51 Length Black
The HUB HRT-5K™ AM Silencer is a compact highly durable 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. These K suppressors were adapted from Griffin’s aggressive R&D project to develop the full-size HRT-556™ AM. Left handed shooters will benefit from the very low backpressure stack as well as right handed shooters. The HUB HRT-5K™ AM is an ideal suppressor for end users desiring an extremely low backpressure suppressor in a minimal form factor thanks to its 4.5″ overall length.
These silencers are built on the industry-standard HUB mounting interface (1.375×24) allowing end users to customize their mounting system to fit their needs. HUB HRT-5K™ AM silencers are compatible with Griffin’s HUB Mount Interfaces as well as other manufacturer’s inserts.
The proprietary patent-pending Nickel 625X™ alloy 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.

What is MAP Pricing?
MAP stands for Minimum Advertised Price. It's a policy set by manufacturers that limits how low retailers can advertise their prices.
The good news? We can often sell below MAP - we just can't show that price publicly. When you request a price by email or add to cart, you'll see our actual (often lower) price.
This isn't a trick - it's how we stay compliant while still offering you the best deals possible.
