It features a full metal body, including the hand-guard, body, trigger, stock tube, outer barrel, flash hider and other external parts.

Geonox Airsoft brings the Delta Armory MK18 AEG to pasture in this gameplay video for those who want to see it action... "In this video I'm playing with my Delta Armory MK18. Normally I'm with 6 midcaps with 120 shots each. In this gameplay we build a MK18 LMG with a 2,500 round box magazine. Should that be banned?"
