Installation of the Front Sight assembly.
1. Drive out the dovetail plug from the gas block (if present).
2. Apply a light coat of lubricant to the dovetail of the hooded front sight
and with a non-marring hammer start tapping the sight into the dovetail
of the gas block from the left side of the gas block.
Note: The right side of the sight dovetail has lead in chamfers to aid
in starting the sight into the dovetail on the gas block!
3. Make sure the sight is straight and not angled as you start it into the
dovetail slot.
4. Use a punch with a diameter large enough to cover the windage screw
hole in the front sight and drive it in until it is flush with the left side of
the gas block.
