[Figured it out, and edited...] The thread sizing for the Marauder de-gassing tool for the Marauder SAM is 3/8-24" The rear spring cap/plug looks like it is the same part between the Marauder's, so it should be the same tool fitment. It's total depth, because of the hammer weight in the SAM being new, will probably be different though There I did get a total depth to 2.465" to the outside face of the plug from the hammer weight's recessed spring hole.

De-Gassing tool is neat but you don’t need it.
Motorhead has tuned hundreds of Marauders and he does not have one.
Just put a wooden rod into the hole (small enough to get through the hammer probe) and press on the valve poppet.
Or, you can take the rifle to ACE Hardware (in a case) and check the threads there.

Fixed it to clarify. The hex key sizes are all American sizing, as well as the SAM being made in the USA, so I would imagine that the threads are all American for our sake.
