How does Airsoft BBs perform rolling testing?

Rolling testing is a commonly used method that can help you detect any irregularities or unevenness in the airsoft BBs. The following are the steps for conducting a rolling test:

1.Preparatory work: Ensure that you are in a well lit environment for easier observation of the surface of the BB.
2.Remove BB: Take out one BB and prepare it for rolling testing.
3.Holding BB: Use your thumb and index finger to hold both sides of BB.
4.Roll BB: Gently roll BB to make it roll back and forth between your fingers.
5.Observing the BB surface: During the rolling process, pay attention to observing whether there is any sense of particle, irregularity, or protrusion on the BB surface. A normal BB should feel relatively smooth during the rolling process, without obvious irregularities or bumps.
6.Check multiple BBs: Repeat the above steps to perform a rolling test on multiple BBs. Ensure a detailed inspection of each BB to confirm if there are any inconsistencies or anomalies.

If any unevenness or irregularity is found during the rolling test, it may indicate defects or gaps in the BB. When purchasing an airsoft BBs, it is recommended to choose high-quality products from well-known brands to ensure that the BB you use meets standards and provides good performance and accuracy.
