There are all sorts of take down rifles ranging from a break action H&R which is less expensive than the ammo you might shoot through it in a weekend, to English made double rifles worth as much as a modest house, with all sorts of black guns and switch barrel bolt guns in the middle, so You need to define what it is you're talking about. The benefits of a take down rifle include ease of cleaning from the breech, being more compact while in transport, and in some cases the ability to have a number of barrels chambered for different cartridges or even shotgun/rifle combinations that can be used with a single receiver.
