How about a Rock Island VR-80 Semi-Auto shotgun, based on the AR type platform. We get them in 12 & 20 gauge. We never had a problem with them and you can get 18 round mags for them. They come with flip up sights and are equipped with picatinny rails for mounting a red-dot. The stock is attached the same as any AR and you can swap them out to fit your style. They have many aftermarket parts available for these guns. Come by Louisiana Gun and we can show you one.
