Two Models, Serious Versatility

The 500 model uses a Superior STX barrel liner, while the 600 model uses a Superior Heavy STX barrel liner—both producing accurate shots that balance a high shot count with impressive power.

The Picatinny optics rail includes a 30 MOA (9 MIL) angle for improved long-range accuracy, with markings on the right side to help quickly reposition optics. Picatinny accessory rails on both sides of the forearm let you add lasers, lights, and more.
