I seriously don't get why people would have any problems aiming. The instruction is simple: Put the front sight right between the aperture of the rear sight; the top of the front sight should line up perfectly with the top of the rear sight; maintain that sight picture while putting the front sight right on the target and squeeze the trigger.

You'll hit your target that way EVERY SINGLE TIME (wind, bullet drop...etc aside for the sake of the point). It's not even about "basic principles of aiming"...it's freakin common sense...I mean they made rear sights for a reason...:rolleyes:

No,

Simple explanation...

Zero your Iron sight
Turn on your optic, zero your optic with iron sight

Your optic is now zero, if you line up, which is fine you will have rear sight blocking it.
