This is a new sighting paradigm, non-traditional. As such, for me it would have to offer clear advantages over other sighting systems for me to consider it. IMO, the differences enumerated in above posts do not qualify it for purchase on my gun(s).
This reviewer, after adapting to some quirks and requirements, found it no faster nor accurate than traditional sights.
Gear Review: Meprolight FT Bullseye Sight - The Truth About Guns
The FO tubes appear to be protected by clear coverings which may make this sight more robust than others with exposed tubes, but I have not found that anyone has addressed this requirement.
The references to this set up being a "mini red dot" sight are mistaken. It shares none of the advantages of an RDS other than having a dot. It is more comparable to a different iron sight system, as it shares the same requirements for precise alignment and similarly occludes the target. It has a narrow window of proper alignment for good accuracy, which makes it the same as traditional iron sights. Because this precise sight picture is different than what every shooter is used to, it is more difficult to use and therefore slower until one has practiced enough with it. Then, switching back to traditional iron sights on another gun again requires some adaptation. IMO, this is not user friendly.
It requires an unusual and unnatural adaptation of focal plane sighting that offers little benefit, especially if one switches between this system and traditional iron sights. Focusing on the close focal plane of the rear sight and the far focal plane of the target are the two extremes of eyesight capabilities. The natural self defense focus on the target will almost certainly degrade accuracy as the circle/dot combination of this rear sight becomes very difficult to retain precise alignment.
Although prices now start around $160 online, it is still expensive for what it offers. It requires the removal of the front sight (apparently after mounting to get accurate alignment) to work properly, leaving your gun looking like it lost something (it did). Yuck.
It is apparently adjustable only for windage, not elevation.
It is big in length and width.
A number of users reported that it is a poor night sight when you can rely only on the little tritium circle as the FO rods do not work in the dark.
In short, this new system with all its quirks and cost does not really exceed traditional iron sights in accuracy or speed performance. It does not compare favorably to the more expensive floating red dot of a true red dot sight system for speed, focus or allowable margin of error.
If you have the extra cash and want to try something new, go for it and report your experiences from first hand knowledge like F16Grinch above, and unlike me offering just opinions without having used the sight. But I would highly recommend you save your old irons, as they will likely be going back on your gun.
