Depending on the magnification power of the scope, you won't even see the front sight post. At a low magnification (3-7x) you may see a slight blur at the bottom of your FoV. Once you get passed 7x the blur is near invisible.

 

The scopes can't focus on light that close to the lens. Due to the convex of the lens, they literally bend light around the post and focus beyond the post. Its similar to how your pistols sights blur when getting a sight picture.

 

Here is a picture to help explain. The focal point would be your target, and the front post would be directly in front of the lens. You can see how much light travels around the front post.

Sheeit, you won't even see the front sight post at 3x.  Sometimes 2x, depending on the scope.  To add to what Rob said, with magnified optics, the scope's field of view is already way beyond the front of the rifle, where that front sight post is mounted.  The scope is already focusing way beyond that distance, which is why it's not even picked up in your vision.

Thanks brother,the money i had was burning a hole in my pocket.So I got the SSA selectror combo.PSA has been filling the shelves on a regular basis.Since I don't build uppers but I do lowers I try to get the best upper assy. I can find.

Brother, uppers are easy - you'd be surprised.  You should give it a whirl.  <thumbsup>

I agree. If nothing else, I think that they go together easier and faster......even with the beer flowin.

I just grabbed a new scope (PA 1-6x24). As I was installing it I thought about this thread. I'm sorry I suck at photos. I hope this helps out some too.

The first pic is at 1x.

The second pic is when the front sight became invisible. It just so happened to be at 3x.

Very cool brother Rob.
