You can choose from the many different customization options available with this type of rifle and create a rifle that is perfectly suited for your unique situation.

The upper receiver by SP is made equal to or above Mil-Spec standards for reliable performance over and over again. The full-length picatinny rail will mesh seamlessly with most aftermarket rail systems to provide the space you need for your optics and other accessories. The traditional design of this upper receiver allows you maximum building options when choosing the configuration of your custom-designed “black rifle”.
