UK Legal & Site Notes
As an internal upgrade component with no impact on chronograph readings or external dimensions, this spring poses no legal compliance issues for UK airsoft play. Most UK skirmish sites accept internal performance upgrades without prior notification, though it’s good practice to inform marshals of any significant tuning. Always confirm your site’s technical rules before attending events with heavily modified platforms.
