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.

The Viper Stock is designed to able to drop into your existing platform. The buffer system is carefully engineered to provide for high reliability while allowing for the use of standard bolt carriers, allowing for multi-role use with a single system. The included flat wire spring increases bolt load despite the compact dimensions for greater reliability, even in extreme short barrel configurations.

In addition to mechanical reliability and performance, we at Strike Industries have also paid close attention to human factors to increase comfort and controllability. The low footprint shoulder weld is shaped to conform to the shoulder pocket for maximum stability and control even in compromised or unconventional shooting positions. Included with the Viper PDW is a rubberized cheek rest to create a comfortable cheek weld, a criticism of many competitor PDW systems.

Finally, a PDW stock without compromise. Strike Hard, Strike Fast with the SI Viper PDW.
