So I was test fitting my new gas tube today, and I have come to realize that while I can get the tube to fit, I have to struggle really hard to get it on an off, and the sight lever actually appears to be digging into the rear of the tube just slightly.
I know that some filing is generally neccesary, but when I compare the saiga gas tube and the ak tube, the saiga doesnt appear to come into any sort of contact with the sight base lever.
When I set both tubes side by side, the ak gas tube appears slightly longer, I have already done some filing to ensure that the tube will fit past the
