Goregous, I especially like the lines of the stock -
Chokes in essence affect the shot pattern by constricting the front of the bore to a certain degree. Fixed chokes imply that there's a fixed constriction at the muzzle; whereas a barrel with choke tubes will have removable chokes, allowing the shooter to vary the constriction at the end. After that there's alot of discussion, arguments, etc...
