See the link below. The information is the same for all Daisy powerline rifles.

Yes.
The current price for the Daisy 880s with scope is about $48
No it's a spring piston system
It was made between 1977 to 1989
Because it is designed to shoot.
I do not recommend it. Its not quite powerful enough

No. Its just a 15 shot BB gun.
NO the Daisy Powerline 1200 is strictly a BB pistol that fires a .175 size BB not a .177 pellet
I suggest you contact Daisy directly and ask for a schematic (see the link below).
