Compatibility & Upgrades
This spring is a direct replacement for the factory nozzle return spring and requires no additional modifications. It pairs well with other Pro Arms performance upgrades, including hop-up units, inner barrels, and piston assemblies. Ensure your gas blowback is functionally sound before fitting – a compromised seal will limit the spring’s effectiveness.
UK Legal & Site Notes
This component is a non-regulated upgrade part and is legal to purchase and own in the UK. Always check your local skirmish site’s rules before fitting upgrades; some venues restrict certain performance modifications. Test your pistol on-site after any tuning to confirm it meets the venue’s FPS limit (typically 328 FPS for pistols with 0.2g BBs).
