I just traded one of my old compound bows to a friend of mine for his 12 guage Mossberg 500. I don't really need another shotgun for hunting, but I thought I could put a little work into it and use it for home defense. It is in very good shape. I am thinking about buying the Bullpup unlimited kit for it. I think it's a really neat kit and I haven't heard of anyone having problems with them. What do you guys think?
