I don't like them. I mean its 7.9 Lbs before optic and the trigger on the ones I have messed with blow ass. Also, for $1,999, you can SBR and AR9, buy a 9mm can and have a nice stubby 9mm AR, suppressed for less than MSRP of that thing. Probably money left over for a PA Micro Red dot or Aimpoint...
