I bought a new gas tube from Tapco. I removed the old gas tube and hand guard and tried to install the new one. It would not fit. So, as instructed by the tapco instructions, I filed the 45% angled notch on the gas tube. After filing it still would not fit so I filed it some more. I've filed it a lot and it will not fit. So, my question is?
1. Do I keep filing?
2. Do I buy one from someone else?
3. If I need to buy another one where do I get it?
Does anyone know if there is an SKS expert out there that can help me with this?
I'm sure someone will suggest installing the old gas tube, but I ruined it when i tried to drill out the end cap pin.
