Making your Mossberg your own by adding accessories and gear to best suit your style and your needs is just one of the many joys of gun ownership. The key is deciding which accessories you do and don't need.
If you need help separating the wheat from the chaff, watch this series of videos from YouTuber TWANGnBANG. In the first video, he reviews the many reasons he chose to use the 590A1 for his tactical shotgun, and in subsequent videos in this playlist he highlights the accessories and changes he made to make it his own.
Though the accessories you decide are necessary for your gun may differ, we hope TWANGnBANG's thorough approach will help guide your decisions.
