Automatic and fully automatic paintball guns

Paintball gun:

The paintball gun is a device that is powered by air and used by players during paintball games to throw paintballs on each other. The term “marker” also used for paintballs is obtained from the history when some group of people used marker pistols for cattle shepherding.

First paintball:

Polystyrene shells were used to make the first paintball that was photodegradable and can easily break into pieces.  Over the year many devices are used to work the paintball that covers a long distance but mostly balls can cover the distance of 100-200 ft. with different velocities.

According to The Paintball Hub, paintballs can travel double the distance with long velocity and more accuracy (25%) by using the technology of fins stabilizing.

Types of paintball guns:

An automatic paintball gun is one type of paintball gun that target every paintball, once the trigger is pulled paintballs are automatically released one after the other with much speed.

Most features of the gun like firing capacity, multiple round bursts, and automatic firing can be increased by providing a marker to the gun.

Using a paintball gun requires some rules to follow:

  • one should fire and only one fire approved the paintball
  • Discharge of balls should be one at a time, and must not be fully automatic
  • Air cylinders and CO2 bottles should be analyzed regularly

Types of Automatic Paintball Gun:

Automatic paintball guns are of two categories,

  1. Electrical paint ball guns are light weighted and use a circuit that is powered by a battery to convert the mode of switch firing into the open fire.
  2. Mechanical paintball guns work on a mechanical system and are heavier than electric paintball guns

Working of paintball gun:

A paintball gun fires by bowling the projectile out of the gun on a jet of pressurized gas. The trigger is pulled by releasing the hammer, which strikes a valve and opens it, releasing a measured volume of gas.

Automatic Paintball working:

Working with an automatic paintball gun is much like an automatic machine gun. Pulling the trigger causes the paintballs to be released continuously till the trigger is released.

Fully automatic paintball guns:

The electronic trigger of fully automatic guns uses a battery of 9-volt power which is rechargeable. The battery is fixed inside the rifle and markers are used for better shooting speed.

Parts of fully automatic paintball guns are easily available so if it is broken down there is no need to worry. Fully automatic guns are used for professional work.

Another form is an electromechanical gun, which has an electronic trigger that electrically discharges the bullet to fire. Because of the lengthier trigger cycle, an automatic/semi-automatic paintball gun fires one shot at a time. A fully automatic gun, on the other hand, may fire more balls when only one trigger is squeezed and released.


  • Accuracy is the great advantage of fully automatic paintball guns as there is no delay of shots and the player can easily change the target
  • There is no need to reload the gun before shooting. Players can load the gun once and fire continuously
  • By pulling the trigger once the player can fire several times almost 30 balls/second before releasing the trigger
  • The battery inside the gun handle can power the marker for faster shooting speeds.
  • 2015 fully automatic Tippmann paintball gun is the best paintball gun yet

Types of Markers:

In terms of working paintball markers has two main types:

  1. Mechanical
  2. Electro-pneumaticA picture containing diagram

Mechanical markers:

Mechanically operated paintball markers employ just mechanical means to fire and do not rely on electro-pneumatic solenoids controlled by an electronic board.

There are five methods of mechanical working:

Pump or Bolt Action: These types of markers were used in the first game of paintball which was played using the Nelson pistol. The mechanism is the same as pump-action shotguns.

Most pump- and bolt-action markers are based on one of two internal patterns:

  • Sheridan Valve: It is named after the Sheridan who first used this design. This type of marker has the bolt used to load the paintball present in a tube. To cock the mechanism, pull the bolt backward, which opens the breech and loads a paintball which causes the hammer to a comeback that automatically pulls back the trigger. Pulling back of trigger causes the bolt to push forward and make the marker fire. Compression of trigger directs the flow of gas from valve chamber to barrel chamber that drives the paintball onwards and ultimately out of the barrel. The process is repeated to fire again and again. Markers that work on this principle are Chipley Custom Machine S6, Worr Games Products Sniper, and Sheridan K2.
  • Nelson Valve: The Nelspot 007 is the first marker that used this mechanism, made by Nelson Paint Company. In this type of marker valve, bolt and hammer are located in the same tube. To allow a paintball to come into the breach, a bolt is pulled. To close the breach bolt and hammer pushed forward and load the ball into the barrel. At this point, the marker is ready to fire. The CCI phantom, Nelson Nelspot 007, and Redux are some examples of markers that work on this mechanism.
  • Sterling “Hybrid” Valve: In this marker, the bolt is located in a separate tube similar to the Sheridan marker and the hammer handles the bolt like in the Nelson valve. Arrow precision Sterling is the marker that worked on this type of mechanism.

Double Action: The markers trigger mechanism both shoots and reset the firing mechanism, similar to how a double-action revolver works. Line SI Advantage, NSG Splat master Rapide, and Brass Eagle Barracuda are a few examples.

Throwback Semi-Auto: In this marker, gases are produced by a valve that reset the firing between shots, the same mechanism is involved in the processing of some semi-automatic guns like AK-47. In Tippman 98 bolt, hammer, and valve all are lineup within the same axis while in King-man Spider bolt is located in a separate tube, and the hammer and valve are in a separate location.

Blow Forward Semi-Auto: The mechanism of fire in this marker works by using the gases which are stored in the valve, gases run the bolt, and then the paintball is fired. For the next shot, a spring is used to repeat the process. Tiberius Arms T8, Air guns design auto mag, and Tippmann X-7 Phenom are some examples of markers that work on this mechanism.Pneumatically Operated Semi-Auto: Between shots, a four-way valve attached to the trigger controls the low-pressure pneumatic piston and repeats the mechanism. These marks can be regarded as semi-auto conversions of pump or bolt action markers. Following are the markers that work on this mechanism: the Palmer’s Pursuit Shop Blazer, Typhoon, and WGP auto-cocker.
