Armaspec HUB Thread Adapter 1.375x24 to 0.9x24

The HUB pattern exists so suppressor mounts stop being brand specific. This adapter carries the 1.375x24 external thread on one end and 0.9x24 internal threads on the other, so a can or mount built around one standard can talk to hardware built around the other.

It is machined from stainless steel, which handles the heat and torque a mount sees without adding much weight out front. If you run more than one host or more than one mounting system, an adapter like this saves buying a second rear cap or a second brake for every rifle in the safe.
