Hey guys,

I have a stamped Mak-90 that I would like to de-ban.  From what I have read a long time ago, Bulgarian AK-47 pattern FSB/Gas Blocks will fit the thicker Chinese AK barrels.  I am looking at these two particular items here:

Anyone have any knowledge whether the diameter of these two parts will fit the Mak's barrel?  

Thanks!

Here is a pic of my rifle, brand new unfired.  Straight cut receiver and enough muzzle material for a proper threading.



Next to her brother, my NHM-90.  Original owner installed an AK FSB though the country of origin is unknown.

They should fit fine on the Chinese heavier barrel.
