Ok my Saiga 12 ran ok out of the box even on low brass . On the 5 rd clip the last round always failed to eject. I bought an auto plug, Tapco puck, Chaos titian quad rail, and a 6 position collapsable stock to dress it up. Now it is under gassed to the point it will not eject any rounds. The Autoplug was screwed all the way down to the highest gas setting and still nothing.
My system is a 3 port gas system that i was able to run a paper clip threw. I have attached a few pictures of the chaos rail. The one rear exhaust port on the gas block appears to be blocked by the quad rail. Could this
