So I got my first AR, I want to put a scope on it, what kind of rings do I need. I have a rail on top. Is the front sight post going to interfere with sight picture? Does it have to come off? It's all new to me.
Cantilever scope mounts were designed with an offset in order to allow the shooter to mount the scope more forward on rifles that do not have a full length rail system in order to get proper eye relief, where conventional rings won't allow. As an added bonus, it does allow you some extra wiggle room access to your charging handle.
Sorry, stole these pics:

American Defence makes the best mounts IMO.
The size of your objective lens will determine the required ring height. All in one scope mount/ring combos like those made by LaRue or ADM are also available in different heights. (and ring diameters). It is possible to use a Picatinny riser to obtain the necessary extra clearance.
Front sight will disappear when looking through a magnified optic
