Arguing that 10.5-11.5" rails is only accommodating a handful of people when they offer a 7" is backwards to me.
Sure, 7" is standard for carbine gas, but A. what percentage of the people that buy a 7" rail are actually willing to take the fsb off and swap the barrel nut for basically zero added real estate and B. Their rail is short and leaves an awkward gap between the fsb anyway. So, still a weird length.
Yes you get a dope barrel nut for your free float awesomeness but how much does that barrel nut REALLY improve over other designs on such a short a** rail.
