The Firefield® Agility 1x30 Dot Sight allows shooters to hunt more effectively with a Remington 870 shotgun. Pairing this device with the Remington 870 provides users a whole new dynamic to this class of hunting gun. The Agility 1x30 Dot Sight is equipped with a built-in saddle mount to securely attach the device to the shotgun and multiple illuminated reticles. Its low-profile design keeps the sight low on the shotgun's barrel, making it less intrusive to your line of sight. The unit also sits closer to the bore, helping to shoot with a more comfortable cheek weld (the position of placing your cheek on the stock of the firearm). Built for customization to the shooter's preference and quick target acquisition, the unit features four different reticles available in red and green: 5 MOA Dot, Circle Dot, Crosshair and Circle Dot Crosshair. Offering a wide field-of-view, the Agility 1x30 Dot Sight features unlimited eye relief for comfortable viewing and is parallax corrected, ensuring the reticle remains in the same spot regardless of target range and aiming position. Engineered with an ergonomic, aluminum housing for exceptional durability and a weatherproof rating of IPX6, this innovative device is nitrogen-filled, fog proof and shock proof, allowing for reliable use in a wide range of Environments.
