Automag (paintball Marker) - Operation

Operation

The Automag uses a blow-forward operation. The idea behind it is to use a constant volume of air at constant pressure each shot, as to exert a constant amount of force each shot, resulting in great consistency. It is also relatively simple:

  1. The trigger is pulled, the sear closes the on/off valve and releases the bolt a split second later.
  2. Compressed air in the dump chamber overcomes the force of the bolt spring, pushing the bolt forward. As the bolt travels forward it seals off the feed port and 'uncorks' from the dump chamber. The compressed air from the dump chamber passes through the bolt and propels a paintball down the barrel.
  3. Once the dump chamber pressure is vented down the barrel, the bolt is returned by a spring.
  4. The trigger is released
  5. The on/off valve opens and re-pressurizes the dump chamber
  6. The dump chamber pushes the bolt forward, which is now held in place by the sear.
  7. The marker is ready to fire again

The design was the original blow forward paintball marker. The design is also used in many other markers. Currently available new markers that use the blow forward system are the Tiberius Arms line of markers, and the ICD Freestyles. The spool valve family of electropneumatic markers is also derived from this blow-forward operation.

Famous quotes containing the word operation:

    “You may read any quantity of books, and you may almost as ignorant as you were at starting, if you don’t have, at the back of your minds, the change for words in definite images which can only be acquired through the operation of your observing faculties on the phenomena of nature.”
    —Thomas Henry Huxley (1825–95)

    “An absolute can only be given in an intuition, while all the rest has to do with analysis. We call intuition here the sympathy by which one is transported into the interior of an object in order to coincide with what there is unique and consequently inexpressible in it. Analysis, on the contrary, is the operation which reduces the object to elements already known.”
    —Henri Bergson (1859–1941)

    “It is critical vision alone which can mitigate the unimpeded operation of the automatic.”
    —Marshall McLuhan (1911–1980)
