Strike Industries announce their Viper PDW Stock can now be pre-ordered for those can't wait. Airsoft players maybe able to install this on gas blowback M4s but they better check it first with Strike Industries before placing an order... "The Strike Industries Viper PDW stock represents the pinnacle of ultra compact PDW systems. At the compressed position, the compact Viper PDW allows for effortless maneuverability particularly in close quarters and vehicular operations.

With the press of a button, the rapid deployment system instantly springs to the extended position for greater shot stability. Previous PDW systems for ARs have been notorious for expensive proprietary systems, spotty reliability and poor ergonomics."
