Femme Fatale Airsoft gets the chance to review this MK18 AEG from Delta Armory and here is what she thinks... "The Delta Armory AR15 MK18 ALPHA is a part of the latest generation of AR15 replicas from Delta Armory. As a part of the ALPHA series, this replica, like the others in the series, is defined by its robust alloy construction. It features a full metal body, including the hand-guard, body, trigger, stock tube, outer barrel, flash hider and other external parts.
