Strike Industries Viper PDW Stock Black - Complete Kit with Stock, Tube, Buffer, and Spring

The Strike Industries Viper PDW Stock is a complete, self-contained AR-15 stock system built for shooters who need serious maneuverability without sacrificing reliability or ergonomics. This isn't a proprietary puzzle—it drops into your existing AR platform and uses standard bolt carriers, so you're not locked into a single-role build. The Viper PDW kit includes everything you need: the stock itself, receiver tube, buffer, and spring, all engineered to work together from day one.

What sets the Viper apart is its dual-position design. Collapsed, it's genuinely compact for tight spaces, vehicle operations, and close-quarters work. Hit the button and a rapid-deployment spring instantly extends the stock for a longer sight radius, better cheek weld, and improved shot stability when you need it. Unlike many competitor PDW systems, Strike Industries included a rubberized cheek rest as standard—a small detail that matters when you're running unconventional shooting positions or working from odd angles. The shoulder weld is contoured to fit the shoulder pocket, prioritizing control and comfort even when the geometry isn't ideal.

The buffer system is where reliability meets compact design. Strike Industries engineered this specifically for short-barrel ARs, using a flat wire spring that increases bolt load despite the compressed dimensions. You get the reliability of a full-size system without the footprint, and without needing proprietary parts. Whether you're running a 7.5" barrel or a longer setup, the Viper PDW was built to handle it.

Frequently Asked Questions

Will the Strike Industries Viper PDW work with my existing AR-15?

Yes. The Viper PDW is designed to drop into standard AR-15 platforms and works with standard bolt carriers. This is a complete system—you get the stock, tube, buffer, and spring all together, so compatibility is built in from the start.

What's the advantage of the flat wire spring in a compact PDW system?

The flat wire spring is engineered to increase bolt load despite the compact dimensions. This is especially important in short-barrel configurations where reliability can sometimes be compromised. Strike Industries designed the buffer system to maintain reliability even in extreme short barrel setups while keeping the overall footprint small.

Does the Viper PDW come with a cheek rest?

Yes. The kit includes a rubberized cheek rest, which is a standard feature designed to provide a comfortable cheek weld—a detail many competitor PDW systems omit.

Can I use the Viper PDW in different shooting positions?

The Viper PDW is built for unconventional and compromised shooting positions. The contoured shoulder pocket and low footprint weld are specifically shaped to provide stability and control even when your shooting geometry isn't traditional, making it well-suited for vehicle operations and close-quarters work.
