Spitfire Armory - EX Tactical Rear Sight - Untapped Receiver for Remington 870, Winchester

This system was the brainchild of Pongratz Engineering LLC and Bernie White, designer of the Desert Eagle to give the old pump shotgun a new lease on life. This fully adjustable Ghost Ring rear sight with fiber optics is ideal for fast target acquisition, specifically in low light conditions. The 5-inch long Picatinny rail makes it easy to mount a scope or red dot sight while the rugged side guard protects the sight from rough handling. Note: It is recommended to have a gunsmith mount the Rail as it requires drilling and tapping the receiver of your shotgun (see installation instructions on Spitfire Armory website) Use this CUT-OUT to check hole pattern with your shotgun: https://spitfirearmory.com/wp-content/uploads/2014/10/Remington-870-1-1-CUT-OUTS.pdf
