A-5 (paintball)
Contents |
Appearance
The Tippmann A-5 is matte-black and resembles the H&K MP5K in appearance. It is extremely popular in MILSIM scenario games due the multitude of aftermarket parts which can make it resemble many real-world firearms. With modifications, it can be made to resemble such firearms as:
Features
The standard A-5 is a semiautomatic open-bolt sear-trigger paintball marker. Standard marker includes single-finger trigger, 8.5" ported barrel, front and rear sights, tournament-legal velocity adjuster, opaque black 200-round wide-mouth hopper and Cyclone-Feed System.
Cyclone-Feed System
Tippmann A-5s utilize a revolutionary concept called the Cyclone-Feed System. It aims to do away with expensive agitating hoppers and electric loaders.
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 loaders, such as the Odyssey Halo) 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, some gas from the trigger pull is routed to a cylinder, which holds a piston. The gas pushes the piston forward, rotating the position of the spokes and feeding paintballs into the chamber simultaneously. 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.
Modifiability
The A-5 is probably the most modifiable paintball marker in existence. Some 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)
Some of the many upgrades include:
- Barrels
- Expansion Chambers
- Compressed Air Low-Pressure Kits
- Camouflage Kits
- Electronic Upgrades
- Triggers
- Tactical Shrouds
- Foregrips/False Magazines
- Stocks
- Body Kits
- Drop Forwards
- Hoppers (due to the unique Cyclone-Feed System, only four hoppers [the stock hopper, Ricochet hopper, TAC-Cap loader, and a 240 round ammo box version] are available).
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 - A-5 Barrel Adaptor, Remote Line, Sniper Barrel (12", 14", 16"), Camouflage Graphics Kit, Double Trigger Kit and Flatline Barrel System.
Flatline Barrel System
The Flatline barrel is the first curved paintball barrel. The slight "S"-shaped curvature, in addition to a roughly honed surface at select points in the barrel, creates backspin on the ball which increases its range by 100 feet over a standard barrel. It is not quite as accurate as many other paintball barrels, but it makes up for this with its added range. Another disadvantage is its tendency to break paintballs more easily. This can be remedied with higher quality paint, however.
The Flatline barrel has a somewhat "intimidating" look to it. The shroud for the barrel looks somewhat like that of a rifle or shotgun, and allows one to hold it as such.
E-Grip
The E-Grip is an aftermarket pistol grip and trigger for the A-5. It features five different fire selections which include:
- Semi-Automatic Fire
- Full-Automatic Fire
- Turbo Fire
- 3-Round Burst Fire
- Auto-Response Fire
(max speed approximately 15 bps)
Response Trigger System
The Response Trigger System is a firing system available for the A-5. The system uses a series of parts that are added to the gun to greatly increases firing rate for the marker. The system uses excess carbon dioxide or compressed air from the firing process to reset the trigger and sear with a pneumatic cylinder. The system can reset the trigger, even with moderate pressure on the trigger. When this happens, the pressure of the finger immediately pulls the trigger back again, to fire again. This effectively gives the shooter the ability to fire fully automatic. As such, it has been banned at some commercial paintball fields.
CAR Stock
A length-adjustable stock similar to the stock found on a M4 rifle. It replaces the endcap of the A-5. It features a ring for affixing a gun-sling.
Construction
Continuing the Tippmann tradition, the A-5 is very durable and features a sold cast-aluminum receiver with a high-impact shock absorbing endcap. The A-5 can take much abuse as all parts are tough and industrially designed. The exceptions to this are the Cyclone-Feed System and the Response Trigger Kit, which both have lines that snake along the receiever and can be snagged easily.
The receiver is held together by five push-pins that can be easily removed to allow easy field stripping. (see Field-Stripping)
Field-Stripping
Unlike previous Tippmann markers, the A-5 is very easy to field-strip and clean. This is done by removing five push-pins on the receiver, allowing it to come apart in two halves.
To field strip an A-5 marker:
- Uncock marker (hold cocking-handle back and pull trigger; allow handle to move to original position) and eject paintball from chamber.
- Depressurize the marker by unscrewing the propellant supply and firing dry to rid marker of any latent gas.
- Remove five push-pins (A, B, C, D and E). Use pliers and lubricate with gun oil if pins are difficult to remove.
- Take apart receiver assembly.
- Clean chamber and bolt assembly.
- Lubricate O-Rings with a few drops of gun oil.
- Reassemble marker and replace push-pins.
Operation
Safety Precaution
Before firing, ensure that approved paintball mask/goggles are worn by operator and all within firing range.
Make sure safety is on, keep finger off trigger and keep marker pointed downward until ready to fire. Do not point marker at anything that you do not wish to shoot.
Propellant
Screw a propellant supply (CO2, N2 or HPA) tank onto receiver or remote coil. Operator should hear an audible sound as marker becomes pressurized.
Hopper and Loading
Press the manual-feed button (located to the right of the receiver, on the Cyclone-Feed System) and check Cyclone-Feed System for proper rotation of sprockets. It should be clean and free of debris.
Attach a compatible hopper to the marker by placing the mouth-end (male) of the hopper into the Cyclone-Feed housing (female) and turning hopper until tab on mouth locks into corresponding hole in feeder housing. Hopper should be parallel with marker.
Open hopper flap and fill with paintballs (up to 200 for standard hopper). Close flap until an auible click is heard.
Preparing to Fire
Cock the marker by pulling back cocking handle. This pulls back bolt and allows access to chamber. An audible click should be heard. Release the cocking handle.
Press the manual-feed button to force a paintball into the chamber.
Turn the safety off by pressing the 'Push Fire' button located above the trigger. A red line on the button indicates when marker is ready to fire.
Firing
Marksmanship is a complex and subtle art and is beyond the scope of this article. However, in general the marker is fired by resting the butt plate or propellant tank against the shoulder, aligning the eye of the firer, aperture of the rear sight, tip of the foresight, and aim to the target, take a breath, and at the end of the breath, squeezing the trigger as smoothly as possible.
Unloading
Uncock the marker by pulling back the cocking handle and pulling the trigger. Allow the handle to return to its original position. If a paintball is inside the chamber when marker is uncocked, it will be ejected through the barrel.
Remove hopper and paintballs from Cyclone-Feed System housing.
Unscrew propellant supply three-quarters of a turn from the marker or remote line. Fire dry shots to rid marker of any latent air and seal valve. Fully remove propellant from marker.
Press 'Push Safe' button to lock trigger and prevent marker from firing.
