A fixed stock that can be adjusted, that's a curious thing and Strike Industries got in the form of the Viper Modular Fixed Stock... "The Strike Industries Modular Fixed Stock combines the versatility and adjustability of a collapsible stock with the strength, ergonomics, and solid fit of a fixed stock. The SI MFS uses a standard carbine length receiver extension and is adjusted using the included shim set to change length of pull."
