A Dumpy Level is an older style level that required 'user' skill to set accurately. Some will have a spirit level to set accurately. An automatic level includes an internal compensator mechanism, which when set automatically removes any variation. Auto levels are thus much easier to use and set up time is a lot quicker
How to transfer an elevation with an automatic level
Sometimes people call it self leveling. Its not really either. If you look at the bullseye bubble on the level, as long as its halfway in the circle, the line of sight won't change. This basically because of comething called a compensator which is a Prism usually suspeneded by wires and maintains the same angle as long as that is within the bubble described, Surveyors like it because if you walk around a tripod and the ground settles a little bit, you won't have to adjust the thumb screws...
because it contain a magnifying glass....
A compensator for looks only. Air soft "weapons" don't generate enough recoil for one to be needed.
The compensator is causing the action to bind, or the additional weight is preventing the slide from moving freely.
No
The noun would be Compensator

I see that the cutts compensator was available on the auto-5 light weight which was made from 1947-1967.I would have to assume that this option was available to the buyer of the sweet-sixteen model also.This compensator was also installed by gunsmiths across the nation.
Improper installation.
It can be done.
