The first thing you want to do is completely
unload and field strip your rifle and remove the
cleaning rod. If you don't know how to do this
view the "Field Stripping" tutorial
on the menu to the right. You will also need the
following tools and parts:
Bare minimum:
A Pin Punch of some kind (an old drill bit that
is slightly smaller then the pins we are going
to tap out will work fine)
A Hammer
Some one or some thing to hold the rifle
A lubricant of some kind, CLP works well
A can of "Break Free" is optional, but
if a part is really hard to move this will help
A Drill
Recommended Extras:
A Vise
A Drill Press with a number of drill bits
A Dremel
Parts Needed:
1/8th diameter wooden/steel dowel rod (any length
over a foot will do fine, I recomend using steel
rods for the FSB) (Note: If you are installing
a threaded FSB you must use steel)
1/8th drill bit

Now we are ready to begin. First view the bottom
portion of the front sight block; you should see
two pins as circled in the picture. If your pins
cannot be seen because they have been welded over
you must file or dremel the weld away. We need to
knock these out before we readjust the front sight
block |
|
|
Most
of the time these pins need to be knocked out left
to right as shown by the arrow in the picture. With
the right side being the ejection port side.
Take your pin punch and hammer and lay the rifle
down on its right side with left side facing up,
it's a good idea to get some one to hold the rifle,
or if you have a vise, rap a towel around the rifle
a secure it. Start taping on the pins with a little
force, not to much at first. Slowly increase how
hard you hit it until they start to come out. |
|
If it doesn't budge at all I recommend covering
both pins and the front sight block in break free
and let it sit for a few hours. Knocking out the
pins is the hardest part, so it might take a little
while. If after both hammering away and soaking
in break free you still cannot get them to budge
try the follow.
1. Insert a steel rod into a drill press that
is the same diameter as the punch and press them
out.
2. Use a plumber's torch or a cigarette lighter
to heat the area and then knock them out.
3. As a last resort use a drill bit of the same
diameter and drill them out.

With the pins out wrap a towel around the front
sight block and lightly tap the front sight block
left and right with a hammer until it breaks free
and moves, be careful, you don't want to bend
it. If it doesn't loosen up and break free do
the following:
1. Soak the front sight Block in Break Free for
a few hours
2. Use a plumber's torch or a cigarette lighter
to heat the area then knock them out.

When the Front Sight Block is loose enough to
be moved left or right set it to the position
you want, obviously if it is canted you want to
set it straight. When you have it where you want
it, lay the rifle on either side and get some
one or some thing to hold the front sight block
exactly where you wanted it.
Take your drill and install the 1/8th drill bit.
Drill out the two original holes to 1/8th.
|
| Now take
your 1/8th diameter rod and cut off two pieces .50
inches in length. Put a tiny bit lubricant down
the re-drilled holes. Grab your hammer and lightly
tap the piece into the drilled holes. Once they
get close enough to the bottom of the rifle base
use your pin punch to finish the job. |
| And that's
it, Reassemble your rifle and your ready to go. |
