I wanted to mount some type of ghost ring sight system and a light on both of my Mossberg Pistol Grip 500s. Originally I thought I could make some type of forward quad rail to hold the front sight and the light. I made a prototype rail but it was just to ugly even for my tastes. Then I was checking out my 930 SPXs and thought "Why not just use a set of LPA sights on the 500s and a simple barrel clamp/rail system for the light" So I ordered 2 sets of sights from PSI and they arrived today. The rear sights took about a minute to install but the front sights will be a little bit more tricky. I have a plan for them but I need some 5-40 bolts and they won’t be here till Monday, so until then I'll just prep everything for the final install.
