16in Saiga 308 Gas Port Diameter/Drill Size?
I have been searching the whole darned internet and on here for days trying to get the correct gas port diameter/drill bit size for a 16in Saiga 308 and I can't find it. If you know it please share it if you don't but you have a 16in Saiga 308 please press that gas block forward and measure your gas port and I will send you a $10 bill to post it on here(please post a pic and describe your method of measurement).
This is aggravating me beyond my capacity for rational thought and held up my skinny barrel Saiga 308 project for almost a month!

Apparently nobody on Saiga 12 forums has ever found a reason to press the gas block off of a 16".Originally Posted by 2ndAmendican
It looks like it's .180" by this persons info, post #8

180 SEEMS LIKE A LOT FOR A GUN WITH THAT MUCH CHAMBER PRESSURE.
IF YOUR USING A LONGER BARREL CUT DOWN THEN YOUR GOING TO HAVE TO USE THE HOLE YOU HAVE ALREADY OR BIGGER START WITH THAT. I DOUBT THE EXTRA LENTGH IS GOING TO MAKE MUCH DIFFERANCE.
I believe that might be the hole in the vertical gas block, even then, that is very large. The gas port in the barrel itself should be much smaller. Somewhere in the 0.060 inch to 0.070 inch maybe, but I don't know what the size is. It might be even smaller. It makes more gas than 223 which would call for a small gas port.
I think it should be around 070 as well maybe smaller . like i said its going to likely be the same in your longer barrel. do not go by the hole in the block its self.
what is the size of the hole on the 22" barrel??????
.180 is bigger thaan what a x39 needs with 15,000 psi less pressure.
The hole size depends on how much barrel is in front of the gas block. If theres only an inch of barrel past the gasblock you would need a larger hole as there is less time to build pressure before the bullet leaves the barrel. start with a factory sixe hole try it and go from there, you can always open it up more.
But that's the problem, no one seems to know what the factory hole size is? Only one person posted info, which no one is sure if it's right, and everyone else seems to be guessing.start with a factory sixe hole try it and go from there,
I tried to check my 22"barrel model, but I'll have to look for something to fit into the 90 degree gas block.
I think a 308 Vepr may have an angled gas block as they are based on the RPK and I think they still have an angled gas port. That would be easier to measure and should be about the same diameter or at least a useable size for a 308 AK build.
