These forearms were designed in conjunction with acclaimed shooter Todd Jarrett. They feature a grip area without rails for a more comfortable feel, unique diamond shaped heat vents, an extended top rail for gap-free installation, “T” marked rails to mark accessory locations, and they utilize our anti-rotation screws for secure installation. The forearm and barrel nut are made of 6061-T6 aluminum and hardcoated to military specifications. The jam nut and anti-rotation screws are steel and plated a matte black finish to match. Assemblies include: one jam nut, one barrel nut, two anti-rotation screws, and one forearm tube.
