Some kind of shotgun

Im not sure what brand this is or what kind of gun its supposed to be,my friend just handed this to me to keep one day. its a basic spring shotgun but very well built surprisingly,im not much of a shotgun person though,it usually just sits around and remains part of the arsenal if i ever need it. everything about this gun is loud,the cocking action makes a loud clinging and it aint suttle when it fires,i suppose if i gave it some mods id carry it with me.
