The Shotgun Saddle Mount from Firefield provides a Picatinny/Weaver Rail for your Remington 870 shotgun. Included set screws replace the trigger pins, to securely attach the mount. The mount has been specifically designed to be low profile, while letting you retain the use of iron sights. Made from anodized aluminum, it is strong, lightweight, and scratch resistant. The saddle mount comes in clamshell packaging with all you need for installation.
