ventilating gas tube


Recommended Posts

jdub if you have a standard ak the gas block will have small holes around the flange where the tube goes on.

 

Either the gas block, or sometimes the tube. But not generally both. It would be much easier to obtain a vented tube, or drill holes in a standard one, than to mess with the gas block itself.

Monty I was wondering if its not vented for a reason. My romainian and yugo ak's are vented. jdub if you have a standard ak the gas block will have small holes around the flange where the tube goes on.

Oh those... Yeah I don't think my Saiga's even have them on the tube or block.

That's exactly what the gas block or gas tube vent ports are for. They don't control gas pressure, like some people beleive. They're there to let excess gas/carbon escape from the gas system. Otherwise, it gets blown past the piston, through the ribbed sections of the gas tube, and into the receiver. This fouls things up a lot quicker than it does with the vents.

 

Some Saigas don't have vented gas blocks. This is just because, so far as I can tell, the factory workers sometimes don't bother with it when the parts are going towards civilian rifles, most of which won't have super high round counts or have to worry about getting fouled up in the field.

 

You can either drill your gas block, or add a ventilated tube. I would suggest drilling the gas block, since all of the "correct" gas tubes for the Saiga series (re: spring-loaded AK-74 type gas tubes) won't have any vents in them.

 

Just take a look at a drilled AKM/AK-74 gas block, and drill in the same spots. Don't drill any further forward than this, as it can affect the gas pulse if you drill into the operating range of the piston.
