Spitfire Armory - MX Tactical Rear Sight for Mossberg 500 and Similar Shotguns
This fully adjustable Ghost Ring rear sight with fiber optics is specifically designed for Mossberg's receiver. It lines up with the stock tapped receiver and doesn't interfere with the thumb safety. You can verify that the hole pattern will work with your shotgun using this CUT-OUT: https://spitfirearmory.com/wp-content/uploads/2014/10/MOSSBERG-1-1-CUT-OUTS-Rev-03.pdf The 5-inch long Picatinny rail is integrated with the sight, making it easy to mount a scope or red dot sight. The rugged side guard is designed to protect the sight from unexpected encounters. (NOTE: Dot will not line up with the ghost ring sight.)
