Re: Best bubble level?
I have two of them ... the B-square and the Vortex , in two rifles .
The B-square is crap . I had to modify the damn thing a lot to make it work on my Weaver rail .
The Vortex is great and fits fine . The only thing is that the ring is too thick and if you are using low rings like me , it touches the rail . Fortunately in my case it seated , but it was so close to the rail that I cut not pass a paper in between the ring and the rail ... the space left between is less than the thickness of a piece of paper , so I did not have to reduce the ring after all .
