I've decided that my next purchase/project is going to be a combat/defense shotgun. I'm leaning towards a Remington 870 as the foundation. My planned upgrades are: 1. AR-style multiposition stock 2. Pistol gripped fore stock 3. Extended magazine tube 4. Red-dpt sight or ghost ring rear sight coupled with luminjous front sight I really don't know much if anything about shotguns. I'm open to any suggestions as to where I should acquire these things. If anyone thinks I'm leaving something important out or should not use one of the items I have listed, please let me know.
