Now that the gear and rail has been swapped over to the new laser it is time to re-install the laser
and rail. Start by fitting the laser U shaped notch back into the lower rail in this photo. Next insert
the top rail into the standoff at the top right in this picture. You will now have the only rear top
standoff, and rail holder to contend with.
Using the same lifting/pressure method as before we need to push the metal tab out of the way.
The rail can then be pushed into place.
Note that the rail is in its spot but sitting there loosely. The metal tab has yet to be locked in place.
