Suppressor CC-BY-NC-SA Remixable Sharable ATF Form 1 Accessory

This assembly jig has two main parts, the Can-side and the Adapter-side, which screw together. The Can-side has an inner taper that matches the taper of a HubTN.4 core, and the Adapter-side screws downward to lock it into place while holding either a HUB adapter attached to a printed mandrel or a tap for HUB threads (1-3/8x24).

Once assembled, it holds everything together in a straight line to force things to stay concentric while the adapter is being threaded for the first time. The jig is not needed in the future once the threads have been cut/chased with the adapter.

Adapting ring inserts for each caliber/model of HubTN.4 are included and allow the same jig to work with all of them.
