The best featureless grip for ar in the market in 2017 - Strike Industries Megafin Featureless AR Grip

I've tried various versions but ended up purchasing three of these. Residing in a state not friendly to 2nd Amendment requires us to search for other options to be in compliance with the law. For those of you wanting to comply, here is the best option for a featureless grip.. (aka...not a pistol grip version) This particular one by Strike Industries called the MEGA-GRIP will have the thumb rest where others out there mostly do not have this feature. It is quite awkward to just have your thumb dangling without a rest since you will not be able to wrap it around like a normal pistol grip version.
With this Mega Grip by S.I., you can actually have some sort of firm grip with your firearm using one hand vs. the other versions. Only negative is it only comes with color black (FDE was suggested to the SI but they said they may consider making one)
