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+ bit/s. Modifications 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. Some of the many upgrades include: Barrels Body kits Camouflage kits Compressed air low-pressure kits Drop forwards Remote lines Electronic upgrades Expansion chambers Foregrips/false magazines Hoppers (due to the unique Cyclone Feed System, very few hoppers [the stock hopper, Ricochet hopper, TAC-Cap loader, X-7 Marker Hopper, 240 round ammo box version, and a 450 Round Offset Hopper] are available); Q-Loader also manufactures a Q-Loader System for the A-5, although it typically requires the right receiver to be milled, unless a custom-manufactured attachment bracket is used. Regulators Stocks Tactical shrouds Triggers A Tacamo magazine kit is available for preorder, which uses functional 18/20 round RAP4 T68 magazines. The upgrades available from Tippmann specifically for the A-5 include the CAR Stock, Response Trigger, E-Grip, Low-Pressure Kit, Expansion Chamber, Universal Mount, 98 to A-5 Barrel Adapter, Remote Line, Sniper Barrel (12", 14", 16" lengths), Camouflage Graphics Kit, Longbow Stock (with or without air-thru), Dogleg Stock (with or without air-thru), Double Trigger Kit and Flatline Barrel System. Flatline barrel system The Flatline barrel is a curved paintball barrel. The slight "S"-shaped curvature, in addition to a roughly honed surface at select points in the barrel, creates topspin on the ball which increases its range by 100+ feet over a standard barrel. Some players feel that it is not quite as accurate as many other paintball barrels, because each paintball is spun differently. Another disadvantage some players claim is its tendency to break paintballs more easily. This can be remedied with higher quality paint, however. The Flatline is also quite loud, due to lack of porting. Unfortunately, Flatline barrels are sometimes considered difficult to remove and clean, though it has been said that the A5 is much easier over the version used by the Tippmann 98 Custom. On the 98 Custom model, they do not screw into the adapter on
