Airosft Pellets

Airsoft pellets are spherical projectiles used in Airsoft gun models. Typically made of plastic, they usually range in size from 5.93 to 5.98 mm in diameter, though select models use 8 mm or 3 mm pellets. They are often called "BBs", referring to the ammunition of more dangerous BB guns (which are actually smaller and made of metal).

Pellet weight is an important factor when choosing pellets. The pellet's weight influences several aspects of pellet performance:


Lighter pellets achieve higher velocities, but are more prone to influence from external factors like wind. Lighter pellets also decelerate (lose velocity) faster than heavier pellets. Due to the increased momentum of a heavier pellet, it will hit harder than a lighter one.


The curvature of a projectile (trajectory) determines its range and lighter pellets result in much more curved trajectories. This can be negated in part by the use of a hop-up.


Heavier pellets may require a more powerful airsoft gun and often necessitates upgraded springs and other gun parts.

A player's choice of pellet weight is governed by their gaming style, airsoft gun (internals), game location (in/outdoor), high/low range and ft/s regulations.

6 mm pellet weights and their usage

0.12 g - Used by some gas and spring weapons. High velocity and low stability. Not to be used in high end AEGs such as Tokyo Marui and Classic Army

0.20 g - Standard weight for most weapons. AEGs uses these or slightly heavier pellets.

0.23 g - Heavier pellets for AEGs. Blends speed of 0.20 g with range and accuracy of 0.25 g.

0.25 g - Heaviest weight for standard AEGs, blowback and spring guns. For some AEGs, you will usually need an upgrade to effectively fire 0.25 inch (6.4 mm) BB's.

0.28 g - Standard weight for highly upgraded AEGs or sniper rifles. Significantly cheaper than .30g , but yields similar performance

0.30 g - Standard weight for most sniper rifles. Western Arms pellets for their gas blowback pistol series. Uncommon.

The BB Calibre:

CYC BB are calibrated to the nearest 1/100mm. This high precision calibration system ensures an optimum trajectory and prevents jamming in the action.

The Roundness:

Inferior BBs can jam in the barrel due to the lack of perfect roundness. Using a BB which is not perfectly round or has burrs on the surface can result in a complete breakdown of the gun and can be costly in rectifying. The choice of correct BBs in the first instance will prevent this. Our BBs undergo a production process which eliminates any uneven surfaces or misshapes and ensures perfect even roundness in each BB.

The Polishing:

Unlike other BBs on the market today which are made from two hemispheres that are then adhered together, CYC brand BBs are made from one piece and then undergo a high polishing process which allows a smooth passage through the internal mechanism of the gun also resulting in more accurate groupings.

Dont ruin your gun with inferior ammo. Re-using old ammo may damage or jam your gun.

How to select the right Airsoft BB

When it comes to Airsoft guns, most enthusiasts tend to think about gun models, gearbox type, Barrel FPS, and battery size. One thing that constantly gets over looked is BB type. There is a variety of Airsoft BBs available, in a wide range of weights, colors, and materials. So, which one do you choose and why is it so important?

WEIGHT - Airsoft BBs are almost always 6mm in diameter, not much selection there. Then it comes to weight, Airsoft BBs start at .12 grams and go as heavy as .36 grams. Save the .12g BBs for your Spring Pistols or low priced, cheap plastic Airsoft guns. Using .12g BBs in metal gear guns is recipe for disaster, plus it will make your gun as accurate as a water balloon launcher. The rest of the BBs weights are personal preference and gun usage. A good starting guideline is a gun that shoots under 300FPS is best served with .20 Gram BBs. Anything that shoots over 300FPS opens up more choices. The heavier the BB, the greater the accuracy at longer ranges. For example, if your using a sniper rifle you should consider .28gram or heavier. For standard field play .23 - .25gram will be fine. Finally, .20 gram will work great in Close Quarters Battle (CQB). Obviously, cost is a factor when choosing your BBs weight. The heavier the Airsoft BB the more they will cost and the more you'll spend on shipping.

MATERIAL - Most of your Airsoft BBs are made of ABS or some sort of plastic. There are a few other types too. The most well know is the Biodegradable BB. They are made of materials that break down when exposed to moisture and light. Some of the Bio airsoft BBs even have an organic Fertilizer core to help vegetation. While these may seem great in reducing BBs from accumulating, keep in mind they do have a limited shelf life. The other material is Aluminum. These are typically BBs that .28g-.36g BBs. They are very expensive but are great for long range shooting.

COLOR - The most popular is white. but really the choice is up to you. Most of the time you want to be able to see where you're Airsoft BBs are hitting, so the lighter and brighter the color the better. If you are doing sniper operations, then you might want to use the darker colored or Black BBs. They will help conceal your location when firing on an opponent.

MANUFACTURER - This is probably the number one criteria in choosing an Airsoft BB. Look for a manufacturer that produces a seamless, highly polished BB. Additionally, the ability of the manufacturer to produce BBs that are consistent in size and weight is equally important. Not only will these characteristics improve your guns distance and accuracy, they will also reduce wear on your airsoft gun's internals. Airsoft BBs by companies like CYC, TSD Tactical BBs, SRC BBs and KSC BBs are of excellent quality. Many of the BBs included with your airsoft gun are of poor quality and should be discarded (our recommendation).

As you can see, Airsoft BB selection is more than buying the cheapest BBs you can find. Consider all the options and you'll maximize your Airsoft gun's ability, accuracy and life span.
