JGH-2 0 Posted April 18, 2013 Report Share Posted April 18, 2013 Has anyone ventilated the gas block? Most ak's have this and it seems it would run cleaner. Any thoughts? Quote Link to post Share on other sites
Sdustin 578 Posted April 18, 2013 Report Share Posted April 18, 2013 Why not jut mod one that's already vented? Like mod it to fit. Seems like it wouldn't be too easy to drill even holes to vebt a non vented one. Quote Link to post Share on other sites
jdub23 21 Posted April 18, 2013 Report Share Posted April 18, 2013 What is this vented gas block you speak of? Quote Link to post Share on other sites
JGH-2 0 Posted April 18, 2013 Author Report Share Posted April 18, 2013 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. Quote Link to post Share on other sites

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. 1 Quote Link to post Share on other sites

Yeah I don't think my Saiga's even have them on the tube or block. Quote Link to post Share on other sites
Sdustin 578 Posted April 19, 2013 Report Share Posted April 19, 2013 i say you should try to get a Chinese tube with the holes and try it i dont see why there would be a problem Quote Link to post Share on other sites
JGH-2 0 Posted April 19, 2013 Author Report Share Posted April 19, 2013 Ok monty. Seems ventilatoin would lessen the amount of blowback into the chamber. Quote Link to post Share on other sites
mancat 2,368 Posted April 20, 2013 Report Share Posted April 20, 2013 (edited) 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. Edited April 20, 2013 by mancat Quote Link to post Share on other sites

jdub23 21 Posted April 21, 2013 Report Share Posted April 21, 2013 I have an old Bulgy ventalated gas tube I might try. Otherwise I would only make alterations to the gas tube, its replaceable. Quote Link to post Share on other sites
