Not sure how you guys can say a front sight doesn't interfere with the sight picture. With my DR I can see my thumb on the top rail when on 1x, the front sight may not stop you from being able to shoot it but you'll definitely see it in the fov and to me that's interference. I don't like having anything but my target in my fov when shooting and having the front sight plain as day blocking the lower half of the crosshairs obscuring the holdover marks would annoy the heck out of me. This is a non issue when switched to 4x but not at 1x.
YMMV
I'll have to take a look when I get home. I've had it for so long I may have just become so accustomed to seeing the front post in the sight picture that I don't notice it anymore.
