AR in .300 Win. Mag.

At SHOT Show, FALKOR DEFENSE called its carbon fiber PETRA .300 Win. Mag. the “apex” of the magnum AR class. It’s equipped with a 20” cut rifled PROOF Research carbon fiber barrel and offers accuracy that FALKOR says has never been experienced in a production AR. It’s built with FALKOR’s patented ambidextrous billet receiver and proprietary recoil reduction system. Unlike its bolt gun counterparts, FALKOR claims the PETRA has virtually no recoil. The PETRA features a Transition MLOK compatible rail so you can add tacticool gizzies, and it’s specifically engineered to add strength and rigidity to the union between the upper receiver and the barrel. Each component is designed with the professional end user in mind and machined to aerospace tolerances in FALKOR’s Montana based headquarters.
