I have one on my custom upper that George Gardner with GA precision built for me and I like it. My intention was to use this primarily as a target gun vs. offhand shooting and that is really where it shines. The trapezoidal shape is not too bad for offhand shooting, but not as comfortable for me as some slimmer grips available (I don't have small hands, but they are not big either, just average). It is very well made and very easy to remove once you install the Badger retaining nut. The rail lines up perfectly with the rail on my flat top receiver and there is no gap at the interface between the receiver rail and the handguard rail.
Like you, I think different is good. I am very happy with the purchase. Hope that helps.
