Strike Industries Stab PDW Collapsible Brace Stock AR15 Pistol AR-15 SI Stabilizer

The Strike Industries Viper PDW Stabilizer represents the pinnacle of ultra-compact PDW Brace 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.

Strike Hard, Strike Fast with the SI Viper PDW Stabilizer.

Disclaimer: Strike Industries always recommends that a certified gunsmith perform all installation of Strike Industries products.

Warning: Disassembly of the stabilizing fin, stabilizer rods, housing, or quick deploy button will result in voiding any and all warranty and customer support from Strike Industries. Do not attempt to alter or modify this item from its intended use. Contact a member of technical support for troubleshooting first.

Note: A non-permanent adhesive may be desired to more securely affix cheek rest.
Note: Not compatible with large frame AR. (LR308, AR10, etc.)

Note: Compatible with Angstad Arms 9mm, PSA 9mm.  The Viper PDW will likely work with any 9mm AR that does NOT use a proprietary buffer assembly.
