Combat Application Technologies AKB 718 Inconel HUB, 7.62mm, No Mount Included, Suppressor

Combat Application Technologies AKB 718 Inconel, 7.62mm, PVD, Suppressor

The Combat Application Technologies AKB 718 Inconel is a .30-caliber rifle suppressor built for use across compatible direct-impingement, piston-operated and bolt-action hosts. This HUB version combines Inconel 718 construction with a 6.04-inch body, a 1.60-inch diameter and a nominal 17.5-ounce weight. It is rated for 7.62 NATO applications, with .300 Winchester Magnum as its maximum listed cartridge.

The AKB uses CAT's SBX internal architecture to manage gas flow and pressure across different rifle systems. Its 1.375x24 HUB interface lets you select a suitable mounting solution for the host. No mount or direct-thread adapter is included, so mount selection is an essential part of completing the setup.

Shop CAT/AKB at BattleHawk Armory and choose the configuration that fits your setup.

Inconel 718 Construction and PVD Finish

Inconel 718 is a nickel-based alloy selected for demanding thermal conditions. In this AKB configuration, the material choice places the emphasis on durability under rifle use. The 17.5-ounce nominal body weight is an important planning figure when considering the overall balance of a suppressor-equipped rifle.

A PVD surface finish completes the suppressor. PVD describes the finish process, while Inconel 718 identifies the underlying construction. Keeping those distinctions clear helps when comparing this version with other materials in the AKB family. The stated dimensions describe the HUB suppressor body; the selected adapter contributes to the completed assembly.

SBX Gas Management Across Multiple Hosts

Suppressor performance depends on more than bore diameter. Barrel length, ammunition and the host operating system all affect the gas presented to the suppressor. The AKB's SBX architecture is intended to manage those pressure and flow differences while supporting a broad .30-caliber centerfire role.

The optimized reference platform is a 16-inch SR-25, with an optimized velocity range of 2,500-2,800 feet per second. These reference points describe the design emphasis, not a requirement that every compatible host be an SR-25. They also do not replace cartridge, barrel-length or mounting requirements for another rifle.

HUB Mounting Flexibility

The rear interface is 1.375x24 HUB. This is the suppressor-side connection for a mount or adapter, not the firearm's muzzle-thread specification. A compatible mounting system must connect that interface to the actual barrel or muzzle device while providing the required internal clearance.

A shared thread designation alone does not confirm complete fitment. Confirm the mounting system's clearance and compatibility with the AKB and the intended host before purchase. Because no mount is included, the HUB configuration is useful when you want to select a mounting solution instead of receiving a fixed direct-thread adapter.

Caliber and Barrel-Length Boundaries

For the Inconel model, the listed minimum barrel length is 13 inches for 7.62 NATO and 5.5 inches for .300 Blackout. These are cartridge-specific limits. The .300 Blackout minimum must not be applied to 7.62 NATO or .300 Winchester Magnum.

The maximum listed cartridge is .300 Winchester Magnum, but that designation does not supply a universal barrel-length allowance for every cartridge within the bore size. Confirm any host combination whose barrel restriction is not explicitly listed. Fitment and rating checks belong to the complete firearm, ammunition and mount combination.

Included Equipment

Included is the CAT AKB suppressor in Inconel 718 with the 1.375x24 HUB interface and PVD finish. A direct-thread adapter, HUB mount and host muzzle device are not included. Select the required compatible mounting components separately.
