AGM now jumps into the HK416 fray, it really is the "in" thing nowadays and Gunner Airsoft has it... "First try to make M4 from AGM, and a really good one. Full Metal construction, and true 416 details on the receiver. Smooth gearbox, 450 fps, just a mini 9.6v battery can operate smoothly. Dust cover and the bolt will open when you pull the charging handle. Light weight CNC`d rail. Bad point : No HK trade mark, they put in the AGM / Commando marking instead. Comes with 8.4 large battery and hi cap magazine."
