Bought a new 18.5" barrel for my recently acquired 500 since the previous owner decided to cut the original ribbed barrel from 28" to 18" and didn't square it off even re-crowned it. Some might not agree but I then converted it to bullpup with the Bullpup Unlimited kit. Currently I camouflaged it, it's toped with a holographic sight and angled forearm grip. Now I'm trying to figure out how to mount a side saddle or even if I want one. Not sure I want to added weight. I just bought a 4-round Tactical Scorpion Gear Polymer 12GA Universal Shotshell Carrier Shotgun. Not sure if I like it or not since it has to be attached to a belt that's at least 1.75-2.00" wide to hold it securely. Thought about a 90 degree offset rail to add top picatinny rail and then attach a 5-round shotshell carrier. Any thoughts on a shotshell carrier or what you might be using and any pictures.?
