300 Whisper AK - Just found a gas block that might be a good start...

I have no idea how many of these are available but I grabbed two of these for my own projects:

Gas block with shut-off valve for grenade-launching Polish PMK (Kbkg60) as seen on page 66 of the Tokoi AK book. Brand new, never assembled. Very rare! $15 each plus shipping. Great for a suppressed AK.

I am pretty sure that these gas blocks will not give us adjustable gas flow as they are made BUT if we were to makie a replacement for that insert that was tapered then an adjustable gas system for the AK is quite possible.... I will not have the money or time to try a 300 Whisper AK anytime soon but this may be a very difficult to find gas block in the future...

Now I need to look into a 223 parts kit (if there is such a beast?) or consider cutting up my SAR-3 or buy another...

Good Luck!
