Letting one of my Unicorns go...this rare beauty is an awesome setup... AR57, AR-57, AR Five Seven on a Aero Precision M4E1 complete lower. Upgraded stock to a FAB Defense and changed out the A2 grip to a nice Fostech overmolded grip. Sightmark Ultra Shot Reflex Sight which I believe is a M-Spec and foregrip bipod combo. Comes with 2 loaded FN PS90 magazines (appx 100 rounds 5.7 x 28mm) and 3 AR57 magazines. Asking $1100 OBRO.
