    I spent a fair amount

    I spent a fair amount of time researching after-market forends for the Mossberg 590 before selecting the Fab Defense PR-MO rail system. Fit and finish were excellent and installation was without drama (check out some of the excellent videos are available on YouTube). Highly recommended if you're looking to add some rail space to your stock shotgun.
