Something for those who want a heavy kicking Colt M16A2 Commando/733 Gas Blowback Rifle can check the Viper Tech Colt M733 Gas Blowback Rifle which claims to have Inokatsu quality. Explosive Enterprises got one for this comprehensive review... "An in-depth review of the Viper Tech (or Vipertech, depending on where you look) gas blowback airsoft replica of the Colt M733, also known as the Colt M16A2 Commando, and more generally the Viper Tech product lineup. This is without a doubt the highest-quality GBBR we've encountered, but that doesn't mean it's perfect."
