Standard thread for 7.62 x 39 is 14mm left hand.
For the 5.45 X 39 AK74 the front sight base has a 24mm right hand thread (Russian and Bulgarian). Romanian 5.45x39 has a 22mm thread. |

Much of the AK100 series has the 24mm FSB for the 7.62x39 rifles as well as 5.45 and 5.56.

I'm not sure, but I think the 24mm thread began with the birth of the AK-74

The larger diameter thread was used to support the much larger, heavier 74 brake.
