Advanced Armament Corp. HUB2K

Where Classic Design Meets Modern Innovation

The HUB2K represents the next chapter in AAC's evolution, reimagining the iconic M4-2000 through advanced manufacturing and modern mounting solutions. The design of this suppressor maintains the beloved silhouette while delivering enhanced performance through 3D printed Inconel construction and advanced internal geometry.

Highlights

• M4-2000 Heritage in a modern body with improved performance
• DMLS Inconel construction provides superior strength-to-weight ratio
• HUB mounting system expands mounting options
• Oversized 6mm baffles reduce end cap strikes
• Full-auto rated for maximum durability
• Direct thread mount with integrated muzzle brake protects blast baffle

A Legacy of Performance

The M4-2000 emerged during the early growth of the civilian suppressor market, becoming a popular entry point for many enthusiasts. Its reliable performance and accessibility helped establish AAC's reputation in an evolving market. The M4-2000's enduring popularity through years of market expansion speaks to its fundamental design strengths. For enthusiasts seeking to complete SCAR-SD or HK416-SD clones, the HUB2K offers an excellent modern alternative to these increasingly rare suppressors, while also upgrading, in terms of mounting, materials, construction and sound attenuation.

Technical Excellence

The HUB2K leverages Direct Metal Laser Sintering (DMLS) technology to print complex internal geometries that would be impossible with traditional manufacturing. The 718 Inconel construction ensures exceptional heat resistance and structural integrity while reducing overall weight. The oversized 6mm baffles represent a significant improvement in durability, particularly addressing end cap strike risks on short-barreled rifles.

The addition of HUB standard 1.375x24 threading provides a welcome upgrade to mounting versatility. This universal standard opens up a broad ecosystem of mounting solutions while maintaining compatibility with legacy systems through included adapters.

The high-temperature Cerakote finish provides additional thermal protection and surface durability, ensuring the suppressor maintains its appearance and performance through sustained use. The included direct thread mount features an integrated muzzle brake that serves dual purposes - reducing recoil and protecting the blast baffle from premature erosion.

Is the HUB 2K a good substitute for the M4-2000 for clone rifles?

The AAC HUB2K suppressor shares several characteristics with the M4-2000 that make it a viable alternative for military-correct rifle builds, but there are notable differences to consider depending on your goals. Here’s an evaluation of how close the HUB2K comes to replicating the M4-2000 for a military-correct rifle setup:

Key Factors to Consider:

Compatibility with Military Standards:

• The M4-2000 was specifically designed for military applications and paired with rifles like the M4 and Mk18. It was often mounted using AAC’s proprietary 51T Ratchet-Mount system, a hallmark of military builds.
• The HUB2K, while incorporating similar robust materials and full-auto ratings, uses the HUB standard mounting system (1.375-24 threads). This offers more versatility but deviates from the strict military-correct setup of the M4-2000.

Aesthetic and Historical Accuracy:

• The M4-2000’s design, weight, and profile were purpose-built for military contracts and reflect the period-correct suppressor for setups like the Mk18 Mod 1 or SOPMOD Block II.
• The HUB2K, with its advanced design and DMLS manufacturing process, appears more modern, making it less accurate for replicating the aesthetic and historical characteristics of the M4-2000.

Sound and Performance:

• While both suppressors deliver excellent sound suppression, the HUB2K uses updated baffle geometry that reduces backpressure more effectively, a feature not present in the M4-2000. This modern design may improve performance but diverges from the authentic military experience.

Weight and Dimensions:

• The HUB2K is lighter and shorter than the M4-2000, which can enhance maneuverability but may slightly alter the handling characteristics associated with a period-correct build.

Overall Suitability:

• The HUB2K is functionally similar to the M4-2000 in terms of durability and suppression capabilities, but it lacks the historically significant mounting system and precise visual design. For a military-correct build, it might not fully replicate the M4-2000's appearance or mounting method.
