Laserlyte Shotgun Tri-Rail Mounting System
When looking for a picitinny rail mount for a Mossberg 500 with an 18.5 barrel and heat shield you will find that there are not a lot of options available. In my search I came across the laserlyte shotgun tri-rail mounting system for the Mossberg 500. What is nice about this piece is that it uses the same holes that mount the heat shield to also mount the picitanny rail mount. This allows you to keep your heat shield while adding a picitinny rail mount which is exactly what I was looking for. The picitinny rail mount installed within minutes with just two screws. The mount seems to be a very sturdy and quality piece but I have not put enough rounds through my Mossberg 500 with it mounted to confirm this. I have approximately 800 rounds through it so far and its holding up great. This may not be the best picitanny rail mount for your Mossberg 500 but it certainly is one of the best when you are in my position. I would highly recommend this mount but advise that if you don't need a heat shield there are plenty of other mounts that I would choose over this one.
