Hey JS-M1A.

Got a Mak-90 and looking to do the exact same thing. E-mail me when you find out who and how to do all you listed. I would like to go halfers to get my Mak-90 done the same way.

Am also in N. Cal.

Just do it yourself with one of these...

If you are doing a Chinese, make sure the diameter is within the spec to thread. If I remember, the Chicom barrels were a little thicker than a Romy or Hungarian. Might need to take off a few thousandths. Use lots of oil and go slow. The tool that goes with the die makes it a no brainer.


Or, a gunsmith will charge you about $25 to $30 to do the same thing.

Good luck

Thank you. Half way there. Now I just have to find the correct
Front sight base. I emailed polytechparts no reply as of today.

Sounds good. I`m scouring the net looking for the correct
Front sight base. No luck with polytech parts so far.
It looks like the euro pattern Ak`s have different sizes
Between the front sight pins than Chicom Ak`s.
I may buy a Romanian front sight base to see if it fits.
I don`t have any romanian parts to compare.
Maybe someone here with romanian parts kit
Could post the pin measurement on the front
Sight base ?

It's 1/2" between the pins on a Romy. Norinco had 3/4" between the pins. You could put an E.German front site block on. These guys sell them.

the Die handle is made in India and didnt fit the the Die.

the customer service is a big fat Zero:mad:
i emailed them with no responce i finally found a contact number.

Called them and he just jerked me around telling me it was the other company thats affilated with him.
No help whats so ever.
I need to contact the Better Buisness Burea.

Sounds like a first rate outfit. I am looking into alternatives.
