What size pin is required to secure an original Russian AK 104/105 Front Sight / Gas Block to the barrel?

Amazon.com.

I've use these on my builds. How many do you need? I have plenty of 3mm x 15mm. How many do you need? I have plenty. I can send you a couple if need it. Just pay $1 for the USPS first class mail and envelope.

Keep in mind that the top pin is LONGER for the FS/GB combo on the Bulgarian FS/GB combo. 3mm x 19mm

I just got my Russian AK 104/105 front FS/GB combo in yesterday and noticed that it does not have a barrel retaining pin hole through the bottom sides of the FS/GB combo. I have seen some original Russian AK 104/105's that had dimples pressed in the sides to secure it to the barrel. I would think the pin would be better but then again what do I know?

Which method of securing the FS/GB combo to the barrel is the Russian factory currently using, pin or dimple pressed fit?

I'm going to SBR a Izhmash SGL 22-94, it has the Bulgarian FS/GB combo. What will have to be done to the barrel and or the Russian FS/GB combo to make it fit and work on the SGL 22-94 barrel?
