Strike Industries built the Pit Viper for folks who want their AR to shed weight and shrink down without turning into a wobbly mess. Machined from 6061-T6 billet aluminum with steel hardware inserts, this buttstock weighs only 4 oz yet holds up to serious use, coming in noticeably lighter than a standard mil-spec M4 stock while offering more durability. The skeletonized, low-profile shape keeps things trim, which makes it a natural fit for lightweight carbines and short-barreled builds where every ounce and inch counts. This one comes in a Blue anodized finish, so it adds a little personality to your build too.
Here's the important part: the Pit Viper does not run on a mil-spec or commercial buffer tube. It's a proprietary design that only mates with the Strike Industries 7-Position Advanced Receiver Extension. That keyed T-slot interface is the whole point. Instead of the usual play you get between a stock and a standard tube, the extra points of contact pull everything together for a fitted feel and a lockup with zero rattle. If you've ever been annoyed by a stock that clacks around on the tube, this system was designed to fix exactly that.
The Pit Viper is essentially two stocks in one. Out of the box it runs as a 3-position adjustable unit with a length of pull that spans 10 to 12 inches, so you can tune the fit to your body armor, layers, or personal preference. Want something even more locked down? Pull the adjustment mechanism, drop in the included fixed-position mounting screw, and pin it in place for a truly solid, no-move fixed stock. It's a quick swap that gives you flexibility down the road.
The orbital stock shape gives you an ergonomic, secure shoulder weld even in awkward positions, which is where a stock like this really earns its keep in tight quarters or off-hand shooting. Ambidextrous QD sling swivel sockets are integrated into both sides, so lefties and righties get a clean, built-in mounting point without bolting on extra hardware. It's a purpose-built piece for a compact, fast-handling AR.
No, and this is the most important thing to know before buying. The Pit Viper is a proprietary design that only mounts to the Strike Industries 7-Position Advanced Receiver Extension. It will not fit standard mil-spec or commercial buffer tubes, so you'll need that specific extension to run it.
Yes. It ships as a 3-position adjustable stock, but you can convert it to a fixed unit by disassembling the adjustment mechanism and installing the included fixed-position mounting screw. It's a straightforward swap that gives you a rock-solid, locked-in position if that's what your build calls for.
The stock comes in at just 4 oz thanks to its skeletonized, low-profile aluminum construction. That makes it lighter than a typical mil-spec M4 stock while still being plenty durable, which is why it's a popular pick for lightweight carbines and short-barreled builds.
In the adjustable configuration, the Pit Viper offers a length of pull ranging from 10 to 12 inches across its three positions. That two-inch span lets you tune the fit for gear, layers, or personal preference before you lock it down.
