This Front sight has a 5-40 thread pitch that is industry standard and will work on a bunch of other shotguns like the Maverick 88. If the shotgun has a thinner barrel profile (Maverick 88), you might have to file down the length of the threaded post so it doesn’t protrude to inside the barrel.
But yes, it should work if the Versa Max 12ga. has the threaded front sight
