RE: paralax free
It took me awhile to understand that one too . Parallax refers to the point of impact in relation to the scope . Since the scope sits higher than the bore you need a point where your reticle and bore intersect downrange . As I gather it , most scopes are parallax adjusted to 200 yards right out of the factory . For ranges above 200 yards you' d need a scope with a parallax adjuster to compensate or your point of impact may shift , especially at high mag . I don' t know of any scopes that are truly " parallax free" . The manufacturer may have meant parallax free within common shooting ranges .

RE: paralax free
Aimpoint scopes are supposed to be paralax free. This is from the aimpoint website explaning what that means.
Because Aimpoint® sights can be used with both eyes open, your field of view is unlimited at any distance. Eye relief is also unlimited, so your eye’s position behind the sight does not affect how well you see the target or the aiming point.
The bright red dot is very easy to see and your eye instinctively aligns it with your target. Unlike the lenses in cheaper red dot sights, Aimpoint’s lenses transmit nearly 100% of all wavelengths of light. This means that colors appear natural and are not distorted. Because of Aimpoint’s unique double lens system, the sights are parallax-free, meaning that no matter where on the lens you see the dot reflected, your point of aim will be your point of impact.
Shots that have to be fired with little time to think are always difficult. At these times it doesn’t matter if the range is short or long or if the target is standing still or moving. It is in such situations that Aimpoint proves its superiority over all other sights.
Illustration 1
This is how the Aimpoint principle works: the red light from the LED is reflected back to your eye from the front lens (double lens). All other light passes through unobstructed.
The difference between
Aimpoint’s solution…
Regardless of where you position your eye, the re flection of the LED is always parallel with the sight’s optical axis thanks to the design of the double lens and its light refraction property. The points of aim and impact always coincide.
…and other sights.
The conventional lens used in the majority of red dot sights gives an angled reflection when the dot is not centered on the lens. The farther from the center of the lens you have the dot, the greater is the deviation from the optical axis. In this case the point of aim and the point of impact can never be the same.
I hope this helps you can find out more on their website. Aimpoint.com
I' ve been looking at these for my slug gun.

RE: paralax free
Most modern, well made scopes exhibit so little parallax that it can no longer be used as an excuse for missing. 
Parallax
A condition that occurs when the image of the target is not focused precisely on the reticle plane. Parallax is visible as an apparent movement between the reticle and the target when the shooter moves his head or, in extreme cases, as an out-of-focus image.

RE: paralax free
Most scopes are set parallax free @ 100 yards, Leupold at 150, and some shotgun scopes at 50.
The easy way to get rid of parallax, is just turn down the power of your scope.
AO objectives do the same, but are seldom worth fiddling with in the hunting field - - - it becomes no particular focus issue until you get past 7- 8X.
No parallax is present on Aimpoint / Red Dot 1X scopes, as there is no magnification.
