Made it to the range yesterday. Gun is all factory gas parts again, G2 trigger that I profiled, polished internals and rails, converted, Chaos rail. Loaded up some #8 Walmart bulk (same thing I've tested with throughout) and was able to blow through about 300 rounds in 4 different mags and a drum without issue. I did have an occasional f up from a couple goofy shells but nothing I can't live with. Now to find a 20 gauge Saiga and start over! Thanks for the help to everyone that pitched in.

Ok, I did a bunch of research and fiddling with my chaos rail. It seems as though my gas block is slightly canted but is not touching the rail. I also found the installation instruction for the rail (Chaos really needs to package those WITH the rail?!?) and found that I hadn't filed the rear hole enough to keep it on a flat plain. Long story short, I think it's ready to go. I'll report back with what I find, hopefully I'll make it out before this weekend.

Ok thanks I'll head home and start searching!

Ok made it back to the range. Put the gun back to stock puck/spring/gas adjuster and hand guard. Performs flawlessly. Put the chaos quad rail back on... Nothing. Every couple rounds I'd get a stove pipe. Took the top off and just had the bottom of the fire grip on and it functions flawlessly again. Full 20 round drums with no issues. So now I need to figure out how to get the chaos to work???

Thanks for the input guys, I will be back on this on Thursday as I'm out town. I'll pull the handrail and put it all back to stock and start swapping parts and see what happens. I'll update as I go.

Sorry guys, I got some bad news yesterday and had to fly out. I'll be back Thursday to get this back on the road. Thanks for all the responses.

I installed the G2 as it came from the package. Once I realized it would need some profiling I went back to the factory hammer to eliminate that as an issue. I will reinstall the factory hand guard and see what happens.

I've cleaned both pucks and ran a bore snake through the gas chamber to make sure all is cleaned. If you shake the gun you can hear the puck rattle back and forth seemingly somewhat free floating??

Yes I ran some other hotter shells, I don't remember what combination was in the gun but yes they ran good. I have put about 600 rounds through the gun with the last 300 all being federal #8s. The spent shells that do eject are usually about three feet forward and to the right of shooting position. But this varies with the combination of plug/puck/spring.

Ok so I put this off as long as possible because I know you guys get tired of the same questions but I'm at the end if my rope with this thing. Here's the details on the gun... Started with a box stock S12 and converted it myself with parts from CSS. I added the Chaos full length quad rail, CAA grip, CSS low brass reliability kit including lighter spring, gas puck an 5 position gas plug. The FCG was moved back to where it was originally and I used the stock insert to add the adjustable stock. The trigger assembly is a tapco g2. So it wouldn't run with the gas plug in any position, I d

Gun won't run for sh!t so I'm trying anything at this point. Guess I'll move on from here and see what else I can figure out. I'll start another thread to explain what I've got going on.

Sorry took a minute to figure out picture posting on this forum. So this is ok?

Here's a pic showing the "D". From what I've read there needs to be a ring above the groove for the plug to seal against?

I will post a pic when I get home. It's not far into the groove but enough the gas plug isn't making a seal I don't think.

Has anyone repaired a gas block that was over "D" 'd? Mine has been filed back into the groove between the threads and the area where the gas hole is. Seems as though they can't be found in the aftermarket. I'm thinking of JB welding it and then filing it back to where it needs to be? Anyone have a better idea?
