The A-5 is a semi-automatic pneumatic marker made by Tippmann for playing paintball. Inspired by the look and feel of the Heckler & Koch MP5K submachine gun, it was first produced in 2002 in the USA. It utilizes a loading concept called the "Cyclone Feed System".
The standard A5 is a semi-automatic, open bolt blow-back operated, sear-trigger paintball marker. Its inline blowback gas system can utilize both CO2 and HPA propellants. Standard marker includes single-finger trigger, 8.5 in (216 mm) ported barrel, front and rear sights, tournament-legal velocity adjuster, opaque black 200-round wide-mouth hopper and Cyclone-Feed System.
Automatic (A-5 with E-Grip only)
Tippmann A-5s use a special paintball feed mechanism called the Cyclone-Feed System. It is similar to electric loaders in that it increases the rate at which the paintball marker can feed balls into the chamber.
Whereas most markers have a feed tube attached to a hopper/loader that either drops paintballs one-by-one or force-feeds (in the case of some loaders) into the chamber, the Cyclone-Feed System is a housing on the right side of the marker. Contained within the housing are two star-shaped sprockets. Paintballs fall from a wide mouth hopper into the gaps between the spokes. As the operator fires, excess gas from the firing cycle is routed to a cylinder, which holds a piston. Gas pressure pushes the piston forward, also compressing a spring which will return the piston when the gas pressure in the cylinder drops; at far end of its travel, the piston is connected to a ratchet which interacts with a toothed gear, the advancement of which on the piston's return stroke [important because it regulates the force with which the paintballs are struck by the spokes] rotates the position of the spokes counterclockwise and feeds a paintball into the chamber. This effectively means that the rate at which paintballs are being fed into the marker is dependent on the rate at which the operator pulls the trigger. Users have reported speeds in excess of 25 bit/s, but this requires mechanical modification to the stock cyclone parts. It is advertised at 15+ bps.
The A-5 is one of the most modifiable paintball markers in existence. Some products are performance upgrades, while others are purely aesthetic. Kits available at many stores and websites can allow the A-5 to resemble many real-world firearms (see Appearance)
