Curiously whats the significance of the dark elite? I havent handled a 220 in over a decade but the beavertail, trigger guard and rails are the first thing I notice (or I think I notice).
i was just reading that the Marines have side stepped the govt process and are beginning to field modified hk 416's. I believe its part of the IAR program
Well this will probably spark some dialog. Its mostly personal preference in an AR. I suspect many AR shooters perform a light crimp. I believe its only mandatory in tube fed guns and guns with decent recoil. Some folks also let the bullet dicatate. If it has a canalure they crimp it.
