I have been looking for info on the internal components of modern rifle scope construction. I am interested in the diffrences in FFP and SFP and just in general all of the parts that go into a good modern scope. I was looking at the cutaway on the nightforce site but I just don't understand which part is moving in a FFP scope.

I always thought it was tiny gnomes with little teeny, weeny chain pulls getting commands through hoses with funnels on the end of them from thescope power gnome, elevation gnome and windage gnome that made my scopes work.

S&B is still using that old gnome technology on most of their scopes, but I heard that in the new 3-20 and 1-8 they were getting with the times and upgrading to Smurfs.

I'm not sure what exactly you are looking for...the diagram above does a pretty good job of showing where the reticle is on a FFP optic. On a SFP optic the reticle cell would be at the rear of erector closer to the ocular. All of that was pretty well covered in my article that Lindy linked in his post also. If you are looking for differences in perspective I have these pictures that show a FFP and SFP at high, mid, and low magnification. I hope it helps.
