Removing the rear sight can be a
bit of a challenge getting it back together is more-so.
To remove the Rear Sight, start
by completely lowering the Rear Sight Aperture into
the rear sight housing by turning the Elevation
With the Aperture bottomed
out, use the Combo-Tool to loosen the screw on the
Windage Knob (right hand knob) by turning it in
a counterclockwise direction. Back this screw all
the way off. It won't fall out but the threads must
be completely disengaged.
When the screw on the
Windage Knob (right hand side) is completely backed
off - hold the Elevation Knob (left hand side) so
that it will not move. At this point turn the Windage
Knob in a counterclockwise direction until it comes
loose and can be pulled off.
The Windage Knob is
then removed from the Sight Assembly.
With the Windage Knob
removed the Elevation Knob can easily be pulled
off of the Sight Assembly from the left.
When both of the
sight's knobs have been removed the next step is
to remove the Aperture.
