I have a stag model 5 with the factory samson star-c isntalled rail. I bought this gun used. Upon inspection I didnt notice there is a slight cant in the quad rail. I mount my red dot m4 on the front rail and 5x magnifier behind it. The my optics shoot low and to the right, I suspect from the red dot being canted to the right on the on the rail. What are somethings I can do to correct this issue? Sould I just deal with it and zero in the red dot as is or can the quad rail be adjusted?
