The Strike Industries Viper fixed stock for AR-15 carbines gives you a solid, no-nonsense alternative to collapsible stocks. If you run a mil-spec carbine receiver extension and want a stock that locks down tight without rattle or wobble, this polymer option delivers the stability of a fixed platform with enough adjustment built in to dial in your length of pull. It's built for shooters who prioritize a rock-solid cheek weld and repeatable positioning over modularity.
What sets the Viper apart is the shim-adjustment system included in the box. Rather than rely on a loose collapsible mechanism, you use the shim set to fine-tune your length of pull before you lock it in. That means once it's dialed, it stays dialed—no creep, no play. The polymer construction keeps weight down while delivering the rigidity you need for precision shooting, whether you're running drills at the range or building a duty rifle.
Strike Industries engineered this stock around the reality that not every shooter wants a adjustable stock. Some prefer the simplicity and durability of a fixed platform that's engineered to fit right the first time. The Viper integrates cleanly with mil-spec AR-15 carbine builds and doesn't require any special tools or adapters to install on your receiver extension.
| Brand | Strike Industries |
| Product | Viper Fixed Stock |
| Compatibility | AR-15 carbine, mil-spec receiver extension |
| Material | Polymer |
| Color | Black |
| Type | Fixed stock with shim adjustment |
The Viper fixed stock is designed for AR-15 carbines with a standard mil-spec carbine length receiver extension. If your rifle uses a mil-spec extension tube, this stock will install directly without adapters or modifications.
The stock comes with a shim set that allows you to customize the length of pull before installation. Once you've selected the right shim configuration for your fit, the stock locks into a fixed position with no adjustment after that.
A fixed stock eliminates the movement and potential rattle of a collapsible mechanism, giving you a rock-solid, repeatable cheek weld and consistent rifle geometry. The trade-off is that length of pull is set via shims rather than infinitely adjustable. For shooters who value simplicity and zero play, the fixed platform is the better choice.
The Viper fixed stock includes the stock assembly and a shim set to customize your length of pull.
