Great buy and best bang for the buck - Tacstar Shotgun Rail Mount With Sidesaddle for 12 Gauge Mossberg 500/590

Definitely my first and only shotgun rail system I will be running. It was super easy to install, the directions were helpful, but in my honest opinion YouTube will probably steer you better along the way. Make sure you definitely have some smaller wrenches for the lug nut closest to the actual shell holder. Also be mindful that you might have to change your sights or get a red dot because the rail rides just a little on the high side which kind of blocks the front sight. Overall great system and I will be buying another one for my next shotgun.
