Back again I have ran over 300 rounds of high brass thru my saiga 12 with a 24inch barrel, and it still wont cycle low brass at all.Ive tried a new twister gas puck and a gunfixers gas plug with no luck. So I called RAA Saiga today, they told me that they have heard of this issue and would send me out a weaker recoil spring. That and making sure the rails are lubed will do the trick, will this work? My saiga only has two ports but I hear that is fine for the 24inchers, the only other change Ive done to the gun was changing the stock to a tapco retractable stock(which I like) any info would be
