I bought a 2008 two port "vodka special" with a canted gas block/front sight (the seller didn't tell me any of that). I sent it to Cadiz to get the warranty work done to it. They drilled the third port but it didn't look like they had touched the gas block that was canted about 10 degrees to the right. I sent it back to get the gas block fixed again, but to my dismay, it is still canted about 5 degrees. I'm tired of sending it off for a month at a time. What can I do?
