    How difficult is this to do? Has anyone here ever done it to a Saiga?

    Did it to a Bulgy AK and a Romanian AK. Not too complicated, but the pin didn't give up easily.

    I suggest getting a punch with the long skinny end on it. I'm sure machinists have a name for it. Make sure it's smaller than the pin hole - like 3/32 or so (?), so it don't get jambed in there (experience talking there...).

    I messed up the first pin so bad the first time (the bulgy) that I had to replace it. Bought a roll pin to replace it with, and filled it with solder after it was installed to make it solid. The second one (romanian), I reused the pin, but paranoia made me put a dab of locktite on it before reinstallation.

    You need a good stable bench vise.

    Can't help with a piston source though. Siaga piston might be longer or shorter than the average Ak....

    Cool...thanks...no Techbrute, I am replacing some of the imported parts with U.S. ones to make it complaint when I mod it to take full house AK mags.

    Only use the 'skinny' punch with parallel sides (pin punch) after you have first gotten the pin to budge using a regular tapered punch. If you start off with the pin punch, chances are you will bend the punch. Also, try tapping from both sides of the pin to see if there is one way that it will go easier. Put some 'Kroil' on it overnight before hammering on it.
