Accuracy in Airsoft starts with good Airsoft BBs. Here at PTS-Steel Shop we only carries precision BBs. Precision BBs provide consistency to prevent jamming and minimum diameter deviation to provide optimized performance.
The chart below is for reference only - the best way to determine the optimized BB weight for any particular gun is to shoot them, as every brand of gun is designed a little differently. You can reach out to our customer service staff if you have any questions about BBs for your particular gun!
