Bruce of BB2K Airsoft checks the DT-4 from Classic Army and the M14 EBR Harvester from Gunfire Custom Division. Any of these can give you double trouble in the field... "Double Trouble at the IWA 2018. At Classic Army, Tobi shows you the heavy guns and I'll show you the Double Barrel DT-4 M4. I also see double at Gunfire and that's not because of the women :-) The M14-EBR Harvester is your ideal companion in a zombie apocalypse. Tobi then shows you the PKP MG from Raptor."
