A direct thread mount is the simplest way to attach a modular suppressor. One end screws into the back of the suppressor, the other screws straight onto your barrel's threads. There is no quick-detach hardware, so it is short, light and cheap. Taking the suppressor off means unthreading the whole thing.
This one screws onto barrels threaded 1/2x28 and into any suppressor with a HUB 1.375x24 rear.
