Finally! Ran her today and did 250 rounds no problem! So pleased, I can finally (after 3 years) called my s12 a completed build. Thanks to all who've helped!!

I've done a full bolt/carrier and fcg glass bolt job, and I'm running magpul flip up sights, could the weight of a holographic sight be part of the issue. I'm about to test fire, so I reckon we'll see! Lol

Thanks bud, gonna test fire tomorrow. Does your saiga run fed low brass with th rail installed? And just out of curiosity do you have a sight on your rail?

Just found a PDF of instructions on chaosinc.com under support, I removed some more material, will try to test fire in the morning. I also plan on removing my eotech for the test, If it cycles fine then I'll reinstall it and test again.

Use a straight edge to make sure the rail is level all the way across you may have to file per the instructions...that was my issue. The back of the rail was binding on the dust cover button. Good luck ! Thanks @sccritterkiller, I'll do that, I've filed the the opening so that the dust cover button can clear. But how much do I take off? Anywhere I might find the actual instructions? I purchased my hinged quad from CSS, and it came with none :/

Having the same problem, ran my 4 port saiga (with oversized port job) today after having installed my sight and and magpul mbus. Fte with every shot (using federal bulk, which ran 100% reliably prior to rail installation). My gas block is at a perfect 90 degrees and rear sight has been removed. I'll use what I've gathered from this thread which seems to be loosening my set screws (the four that hold the top rail in place) and blue loctiting them. Then dry cycling shells by hand to see if they are striking the top rail (which I assume would be causing my fte's?) I'm a new member who is simply
