I understand they both drop fps, I also read that it is damaging. If this is incorrect I'll be grateful for the correction. and this is from memory.
The short barrel means the resistance applied to the piston and spring will be removed once the bb leaves the barrel. Because the spring hasn't met full potential at this point (and from what I understand because it isn't moving at full speed in the beginning while the bb is being launched is why it loses fps) the full force of the piston and spring slam into the mechbox essentially as if you were dry-firing. And that would be bad.
If not then you helped debunk another airsoft myth
