Why use a cantilever mount?

  1. Firstly, the fact that the cantilever mount pushes the optics a bit forward not only offers a better eye relief and field of view, but also clears a bit of space on the rail in the back of the rifle, making it possible to mount something else in that spot, for example, magnifiers or folding back-up sights, and so on.
  2. Secondly, a scope, especially a full-sized scope that one would mount on an AR-10 or other DMR type rifles, is a rather heavy piece of equipment. The further you push it on your rifle, the greaterthe lever you create, making the rifle feel heavy and unstable. Bringing the point of weight backward towards yourself makes the rifle much easier to handle.
