In-Line Regulator
A regulator that is situated in-line, either under
the grip or in the front of the marker. It takes
stepped-down pressures and converts them into a
consistent working pressure. This allows your marker
to work at lower pressures, decreasing paintball
chops and wear and tear to your internals(see below)
and increasing consistency. The in-line regulator
can also be used to regulate velocity.
Internals
The internal working parts of your marker.
Laying the Paint
No, this is not a sequel to American Pie (don't
you know that broken shells scratch?). Laying paint
refers to the art of letting off many paintballs
in a stream of gelatine and dye.
Lighting Up
The practice of really letting someone know they
are out. Often seen in tourneys when there are old
grudges to be settled. This can attract penalties
in tourneys although it is hard to prove.
Loader (Guppy)
A tube-like device with a clip top that is used
to carry paintballs onto the field. Loaders come
in various shapes and sizes.
Long-Ball
You will be astounded to find out that long-ball
refers to the act of shooting at extreme range.
Low-Pressure Regulator
Used in markers with automatic cocking (i.e. not
blow back/forwards). A low pressure regulator steps
down (decreases) working pressures to even lower
pressures to drive the re-cocking of a semi.
