So, I bought a mossberg 500 Flex for my first shotgun thinking this new flex system would be nice to switch parts around with ease. Now that I have this shotgun I've been searching the web and it seems there are not really many options out there. Whats the deal? I almost wish I would have gotten the regular 500 as there is a lot more forearms, stocks and pistol grips available. Anybody know when more after market products will be available?
