I use a Daisy Red Ryder BB Gun.
probably an ak-47 model
A tiny bit less than a maxi gun.
For an air/piston powered .177 BB gun - anything less than 200 feet per second (fps) For a CO2 powered BB gun - anything less than 300 fps. For an "AIR SOFT" gun - anything less than 150 fps.
A gun is not that safe because of its killing affect. A gun is simply a tool, no more or less dangerous than the person who has it.
Gun shops, gun shows, want ads.
Less than 1 %
Yes they have less impact.
Less than 1/2 second
Depends on the exact gun. A 12.8 CM gun is 128mm. Generally will have less range than a 155, but depends on WHICH 155, and WHICH shell it fires.
Value can range from less than 100 to more than 1000 USD
While velocities vary from model to model, an airsoft gun is usually safer than a bb gun because a plastic ball is less likely to penetrate an object than a steel bb.
Depends on the gun. I have one that weighs less than one pound, and one that weighs 23 pounds. There is no one weight.
