Double Eagle M906B - Upgrade and Range Testing

This is a Double eagle M906B airsoft AEG that I have done some upgrades to then had a chance to test at Worthing Airsoft! trying to achieve best performance from the airsoft replica. More FPS, More range

Thanks to Worthing Airsoft for the use of their range. Be sure to check them out! https://www.worthingairsoft.co.uk/
