The key to powerful BB Guns? A strong and reliable motor. At Just BB Guns, we consider a motor to be the hardest working component in your electric gun. Whilst standard factory-fitted motors are a great starting point, if you want a truly elite performance, you may wish to consider upgrading your motor. Top tip: If you hear a whining or scratching noise coming from your Airsoft Gun, it’s time you look at replacing your motor! If you upgrade or replace your motor, you must ensure you have a compatible gearbox. The gears & motors must work in harmony to ensure your weapon is as powerful and accurate as possible. Unsure which gears & motors are right for your weapon? Get in touch with Just BB Guns today. Every member of our team is an electric airsoft gun expert and can help you find the perfect gears and motor for your weapon.
