HOP UP TEST
In our Hop up test, we use a simple method to evaluate the performance of an airsoft replica's Hop up mechanism.

The test covers the entire range of standard BB weights from : 0.2/ 0.23/ 0.25/ 0.28/ 0.3/ 0.32/ 0.36/ 0.4/ 0.43/ 0.45/ 0.48.

Through this test we are able to precisely determine the heaviest BB weight the Hop up is capable of lifting.
RANGE TEST
The range test defines the maximum effective range out of an Airsoft Replica.

Using our indoor 70M windless shooting range and camera equipment, we can clearly track the BB's trajectory and how far the airsoft replica is able to shoot, meanwhile also observing the accuracy at each distance.
GROUPING TEST
The grouping test helps us define the accuracy of each airsoft replica.

The test covers all kinds of guns, and the result would show the difference by comparing a stock platform to an upgraded platform.
SPEED CONSISTENCY TEST
The Speed Consistency Test is conducted in 3 different temperatures in side our temperature controlled chamber. Test Ranges from 40 c for high temperature/ 25 c for standard temperature / and 10 c for low temperature.

This will help us to see how well an airsoft replica can perform under certain temperatures.
GAS EFFICIENCY TEST
In order to find out how well and how efficient an GBB airsoft replica can shoot, we will set the gun into our temperature controlled chamber at 10 degree Celsius and calculate the efficiency out of each platform.
ROUNDS
PER SECOND
TEST
For this test we will use high speed camera and glow in dark bbs to find out how many rounds can be fired within an second
POWER EFFICIENCY TEST
We are able to define how efficiency each AGE is, throughout our testing method we are able to precisely define the energy used for each shot, and also see how battery power changes when firing full auto.
