The Strike Industries Viper PDW Stabilizer 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 and faster reaction time. Previous PDW systems for ARs have been notorious for expensive proprietary systems, spotty reliability and poor ergonomics.
This system is designed to be able to drop into your existing platform. The buffer system is carefully engineered to provide 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.
Included with the Viper PDW is a rubberized cheek rest to create a comfortable cheek weld, a criticism of many competitor PDW systems. At the rear of the buffer tube and beneath the housing, QD cups are built in for expanded sling mounting options.
Unlike most traditional arm stabilizers, the Viper PDW Stabilizer is designed to be ergonomic and comfortable along all planes. The overall design eliminates any snag hazards and abrasion zones resulting in a comfortable cheek-weld and stabilizing interface.
The PDW Stabilizer is already ATF approved. Finally, a PDW stabilizer without compromise. Quickly deployable, drop-in capable, and ruggedly reliable.
