The first thing you want to do is completely
unload and field strip your rifle. 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:
A Pin Punch of some kind (an old drill bit that
is slightly smaller then the pins we are going
to tape out will work fine)
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 with a 1/8th inch drill bit
A Drill Press with a number of drill bits
Before we replace the Front Sight Block I must
mention a few things. Because of a cool technicality
in the law you can put a Romanian Threaded Sight
Block on a SAR-2 rifle because of its odd thread
size. This is legal because the threads are on
the sight block, not the barrel, and the fact
that it is threaded with 22mm threads, which currently
there are no sound suppressors, or flash suppressors
designed with that thread size. Here is a link
to the BATF ruling that this is legal.

Now with a threaded Sight Block on a SAR-2 (sorry
but they only fit 5.45*39mm AKs with out modifications,(.223
AKs might work but I am not sure), though I have
heard that 7.62 versions exist) you can use a
Romanian Muzzle Brake that is threaded in 22mm.
With a threaded muzzle brake you can take it of
and put it on whenever you want to, now welding
in place! The only thing you have to watch out
for is your US parts count. With a foreign muzzle
brake attached you have to replace at least one
more foreign part on your rifle with one made
in the US.
Ok now that that's out of the way we can begin.
First below is a list of parts you must have to
install a Romanian Threaded Front Sight Base.
1/8th diameter wooden dowel rod (any length over
a foot will do fine)
The following parts can be purchase from K-VAR
AK167 - Front sight block
AK205 - Retainer pin, w/spring for muzzle nut
AK256 - Retainer pin, for AK74 plunger pin
AK141 - AK74 Romanian Compensator (if K-VAR is
out of these I think Global
Trades sells a US version in 22mm)
Ok first you must remove your old Front Sight
Block. To do this you must remove the two bottom
pins that hold the Front Sight Block on. To learn
how to do this visit the Fixing a Canted Front
Sight Block tutorial which can be found on the
menu to the left. Once the pins have been removed
return back to this tutorial. Also another option
to removing the pins is to just cut the old front
sight block off with a dremel. I don't recommend
you do this but it will work, just be sure not
to cut your barrel in the process.
With the pins now removed make sure you scribe
on the barrel the locations it is at. Take your
hammer and tap the front sight block off, that
is if you didn't cut it off already. With the
old front sight block removed, take a little bit
of your lubricant and lightly coat the front of
the barrel up to the part where your new front
sight block will go.
Now your ready to install the Threaded Front
Sight Block onto the rifle, first slide it onto
the barrel and lightly tap it into place with
a hammer until its in the same position that you
scribed on the barrel where your original front
sight block was. Be very careful not to mess up
the threads with the hammer.
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
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 steel pin 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.
take a look at the threaded front sight block and
look at it from the rear; you will notice that there
is a hole above where the barrel fits. This hole
is for the Retainer pin that locks the compensator
in place, but it's missing so we must put it together.
The rear hole is where you insert all the parts
from, the front hole is where the plunger comes

the spring and retainer pin that came with package
AK205 that you ordered from K-VAR and drop the retainer
pin, with the open end facing to towards the rear
of the front sight block down into the hole, now
drop the spring down inside the hole also. View
the picture if you need help.
need to lock the piece in place, take part number
AK256 that you ordered from K-VAR and put it in
the small hole circled, use a small punch to put
it in place, you may have to use another punch to
push the spring out of the way, make sure that the
compensator retaining pin and spring are still inside
the front sight block. When the pin is in place
push in on the compensator retainer pin, if you
did this correctly it should have some spring tension
behind it. The ends of part number AK256 should
be cupped out to hold itself in place, to secure
it we must flatten both ends on each side. Look
at the picture below.
flatten the ends of the pin out you must place one
side of the pin against a flat hard metal object
and tap of the opposite side with a pin punch to
get it to flatten out, when you are finished on
one side switch sides and do the other. View thepicture
to get an idea of what it should look like.
And lastly, take a dremel, or file and grind
off the Bayonet lugs if your threaded front sight
base has them. You must do this to be legal.
it, Reassemble your rifle, put the compensator on,
yand your ready to go.
