Specna Arms AEG Spring

If you like to tinker with your Airsoft AEG and need to fine-tune its FPS, maybe this will do the trick! The Specna Arms Spring has different strengths for better power tuning. If you're struggling with a platform that is too hot or too weak for the UK power limits, this could be the best place to start in helping it be site legal. It should be compatible with most Airsoft AEGs, certainly those with standard V2 gearboxes. If you need a new spring as a replacement or like to stockpile spares in case of the worst, the Specna Arms Spring is a great thing to have in the toolbox!
