What airsoft gun manufacturer uses the "ns2" gas system in some of their gas guns?
Correct Answer
C. KWA
Explanation
KWA is the correct answer because they are known for using the "ns2" gas system in some of their gas guns. The "ns2" gas system is a proprietary system developed by KWA that provides improved gas efficiency and performance in their airsoft guns. Tokyo Marui, Echo 1, Well, and WE are not known for using the "ns2" gas system in their gas guns.

Name the three gears in a typical AEG gearbox, in order of contact from the motor (pinion gear) to the piston:(Answer in this format, keep all lowercase: first, second, third)
Correct Answer
bevel, spur, sector
Explanation
The three gears in a typical AEG gearbox, in order of contact from the motor to the piston, are bevel, spur, and sector. The bevel gear is the first gear that comes into contact with the motor's pinion gear. It transfers rotational motion to the spur gear, which in turn meshes with the sector gear. The sector gear ultimately drives the piston, allowing for the compression and release of air in the gearbox to propel the BB.
3.
Which of the following springs would cause the most even (or possibly least) amount of wear on the piston/gearbox:
Correct Answer
B. PDI 150%
Explanation
The PDI 150% spring would cause the most even or possibly least amount of wear on the piston/gearbox. This is because a higher percentage spring indicates a stronger or stiffer spring, which means it will provide more consistent and powerful compression. This consistency reduces the chances of the piston or gearbox experiencing excessive strain or wear, leading to more even wear over time.
4.
What is a possible cause of a high pitched whining sound in an AEG?
Correct Answer
A. Motor Height
Explanation
Motor height refers to the adjustment of the motor position in an AEG (Automatic Electric Gun). If the motor height is set too high, it can cause a high pitched whining sound. This occurs because the motor is not properly engaging with the gears, resulting in a strained and noisy operation. Therefore, motor height could be a possible cause of the whining sound in an AEG.
5.
Which of the following brands make both spare magazines and BB's?
Correct Answer
C. Echo 1
Explanation
Echo 1 is the correct answer because they are the only brand listed that makes both spare magazines and BB's. The other brands listed may make spare magazines or BB's individually, but not both.
6.
What material is G&P's famous "white" piston made from?
Correct Answer
E. Polyacetal
Explanation
G&P's famous "white" piston is made from polyacetal. Polyacetal, also known as polyoxymethylene (POM), is a high-performance engineering plastic that is known for its excellent mechanical properties, such as high strength, stiffness, and dimensional stability. It is also resistant to wear, moisture, and chemicals, making it an ideal material for pistons in various applications, including airsoft guns.
7.
How long is the inner barrel of the Tokyo Marui G36C (the JG and Echo 1 G36C as well)?
Correct Answer
C. 247mm
Explanation
The correct answer is 247mm. This measurement refers to the length of the inner barrel of the Tokyo Marui G36C, as well as the JG and Echo 1 G36C models.
8.
When storing (a) gas magazines...
Correct Answer
D. Remove all BB's and pressurize the magazine
Explanation
Storing gas magazines requires removing all BB's and pressurizing the magazine. This is important because leaving BB's inside the magazine can cause them to jam or damage the internal mechanisms. Pressurizing the magazine ensures that it is ready for use when needed. Storing the magazine in sunlight is not recommended as it can cause the gas inside to expand and potentially damage the magazine. Throwing the magazine against a wall is not a proper storage method and can lead to damage.
9.
What material is most commonly used for the barrel of airsoft guns?
Correct Answer
B. Brass
Explanation
Brass is the most commonly used material for the barrel of airsoft guns. This is because brass is a durable and corrosion-resistant alloy made of copper and zinc. It has excellent machining properties, allowing for precise manufacturing of the barrel. Additionally, brass has good thermal conductivity, which helps dissipate the heat generated during rapid firing. Its properties make it a suitable material for airsoft gun barrels, providing reliable performance and longevity.
