The Genesis Arms HUB to SGX Adapter is a mount adapter that lets a GEN-12 shotgun with the 1.375-24 HUB muzzle thread run JK Armament SGX suppressors. JK Armament introduced its SGX series of 12-gauge suppressors in early 2023, and they use a proprietary mounting interface that differs from the HUB pattern on the GEN-12 SBM models. This option from Genesis Arms takes the GEN-12 from HUB to SGX. It is a heat-treated 17-4 stainless steel part that is CNC machined. For a GEN-12 owner who wants an SGX suppressor, this is the adapter that bridges the two.

Key Specifications

• The adapter option is HUB to SGX, which converts the GEN-12 HUB muzzle thread to the SGX mount.
• It works with JK Armament SGX series suppressors, which use a proprietary SGX mounting interface.
• The GEN-12 side is the 1.375-24 HUB thread found on the GEN-12 SBM models, the common HUB suppressor pattern.
• Material is heat-treated 17-4 stainless steel, a strong grade for a mount that carries a suppressor.
• It is CNC machined, which keeps the threads and mounting surfaces precise.

Frequently Asked Questions

Which GEN-12 models does the HUB to SGX adapter fit? Genesis Arms describes it for GEN-12 models with the HUB muzzle thread, such as the SBM models, which carry a 1.375-24 thread so they can direct thread HUB suppressors.

Why would I need an SGX adapter? JK Armament SGX 12-gauge suppressors use a proprietary SGX mount instead of the HUB pattern, so a HUB-threaded GEN-12 needs an adapter to accept them.
