A request for a little education - I've just started thinking about getting a tactical shotgun - is the one in the picture a Mossberg or a Winchester or a Remington or something else? It is a 12-ga, isn't it? What is the thingy on top? Is that a Surefire up front, or something else? What kind of shot is in the shells? They are 2-3/4" cartridges, right? Thanks...
OK, so it is a Remington 870... Now for the other questions...
