The Definition of Takedown
A firearm that can be separated into (at least) two subassemblies in order to make a shorter package than when put together, without tools.
There is no specific requirement regarding how this disassembly must be accomplished; the mechanical design is up to the creativity of the maker.
This arrangement allows for more convenient transportation of a firearm, but with rifles, where the action normally separates from the barrel, usually at a small sacrifice in accuracy.
Takedown firearms can also be called take-apart firearms.
Good examples of a takedown guns are the Henry AR-7 Survival Rifle, the Ruger 10/22 Takedown or the TNW Aero.
