How do you turn your fps up on a paintball gun?

Answer 1

The answer to your question is: it depends on the style and manufacturer of your paintball gun. With that said, there are a number of "standard" ways to adjust velocity.

One of the common ways is inserting an appropriately sized Allen wrench into a small hole often located on the side or out the back of the gun. Turn it one way or another to raise or lower the velocity (on Tippmann 98s the hole is in the side, on most new spyder markers it is in the back).

Other guns use a knob in the rear of the gun, you simply turn it one way or the other. These knobs are usually secured with locking mechanisms; generally either a small screw or a hex nut. These locking mechanisms prevent accidental velocity adjustments as well as prevent unscrupulous players from turning up their velocity after it has been check by a referee. Fields most of the time require some type of velocity securing device if the gun has an easily adjustable knob. Recently, this type of adjustment has been given up in favor of just put a hex (Allen wrench) receiver on the back of the gun.

One of the more rare adjustments requires a long metal hex rod to be inserted down the barrel, from there it makes contact with an adjustment receiver and velocity can be adjusted by rotating the rod left or right. Many older pumps used this method of adjustment, and it can still be found in higher end models, namely phantoms.

On many entry-level markers, there is no velocity adjustment. This is the case on many brass eagle products, however most of these guns already shoot below the 300fps mark, so you shouldn't have much to worry about.

If there isn't a velocity adjustment on the gun, you still have a possibility of changing it. Velocity adjustment is usually the result of changing the tension on a spring located inside the gun. You can make velocity adjustments by locating this spring and replacing it with a spring of higher or lower tension. This can be a complicated process, and you can damage your gun if not done correctly. There are also other parts that can be adjusted or replaced to change velocity, but again, this gets pretty complex and you need to know what you are doing.

A few final thoughts; remember velocity is a combination of a number of factors. Especially if you are using CO2 then temperature can wreak havoc on your velocity. Also, if you get shooting quickly liquid CO2 will start to enter your gun and your velocity will drop off quickly. My advice for both of these problems would be to buy an insulated bottle cover as well as install an expansion chamber on your gun. Another solution, if your marker accepts it, would be to switch your gun to compressed air, this will keep a more consistent velocity than CO2. Also a well maintained gun will hold velocity better; remember that you gun is full of rubber O-rings that wear out over time. A good seal on all your rings will keep your marker firing at a more consistent velocity. Finally, keep in mind that at NO TIME should ANY marker be allowed to fire above 300 fps. This is the threshold that goggles are designed to withstand, as well as it starts getting into the realm of injury when you get hit.

IF you know what your are doing than the above is a good answer but obviously u dont or else you woulndt be asking, so BEFORE YOU DO remember all paintball guns are designed to operate at an optimal range if you change it too much you can damge things like o-rings and the valves or even the bolt which in that cass throw the gun in the trash.
