Lots of fitting, but the least worst option - NcStar SKS Gas Tube Scope Mount w/ Side Rails

This product is heavy. The gas tube has been reinforced with ribs, which is probably good to keep it stable, but it is going to add some weight. As the description noted, it is long and will require some filing. Alot of filing for my Chinese SKS, but I went slow and I have a very tight fit that will certainly help keep this stable. The original gas tube was very sloppy, so I advise to have fit and don't make the same as original. The set screws seem sloppy and should definitely have loctite added. What I didn't expect was having to sand the ID of the piston part of the tube. The paint was thick and had to be removed to get the piston to even insert. I don't expect a gas tube mounted optic to hold a great zero, but it is much better than I expected once I achieved the fitment I wanted.
