I put a scope on my AR15 (flat top without the carry handle) and The front sight is right in front of it it so i thought I'd need to get something to elevate the scope over it but when I look through it I dont see my front sight at all. Any explanations? cause I got no clue.

Is there a complaint here? Is it accurate?

If its accurate, and its not obstructing...
I understand your confusion. When my manager told me I got an extra 500 bucks in a sale yesterday, I was a bit confused too, but it's one of those things where you just take what you get while its good man.

It probably has something to do with optical refraction hocus pocus. I can't see my finger in front of a pair of binoculars unless I put it right on the lens.

It's due to the magic of optics and focal point (length) of the scope. In a multi power scope, e.g. 3x-9x, the light is being collected by the objective lens from a point beyond the front sight and focused on the ocular lens as a pin point. In a sense, the scope cannot see the sight post. Obviously when using a 1x powered red dot the sight post is visible for co-witnessing through the sight tube.

Yuppers -- it's way out of focus and probably only takes up a small part of the bottom half of the overall sight picture anyway.

ive heard any magnification under 3x will give you at a minimum a shadow on the bottom where the post is. but above that its as if its not there. wont effect accuracy or anything. just one of the little magic things that happen.

I will explain this in a way most will understand. Your scope magnifies whats on the other side. A 4X scope shows you whatever you are looking at as if you were 4X closer...so an object 100 yards away looks as if it was only 25 yards away...4X closer. If using a 10X scope the same image would appear to be 10 yards away. Now keep in mind EVERYTHING in front of the lens is seen as it would be at the distance you are looking. So when you are looking at a car 100 yards away, even though you see the car at X times closer...the front post of the AR15 is also seen as if it was 100 yards away, which will be nothing but a blur or black spot. Now when you use a scope to view an object too close all you see is a blur because its like you walking up to that object and placing it up to your eye...you are too close to focus your eye on it. In the case of an AR15 with scope both the A2 front post and the too close object mush together since both are now viewed as if they were too close for your eye to focus on.
