You might try this ...

Export* the table & guns as a Wavefront OBJ... *(Include Group info)

Import what you just exported ... UNcheck everything on Import so the scale is not changed.

Save the Imported (compound) object in the Props Library

Then Load as many tables (with guns) as you need and position them where you want.
