The graduated winding pattern reduces stress on gears and motor while maintaining stable output around 120 m\/s. Factory pre-tensioning ensures reliable performance from day one, resisting tension loss and fatigue that plague lower-quality springs—even under sustained high-rate-of-fire use. The compressed end with tighter coils installs onto the spring guide. Compatible with most standard AEG gearboxes (V2, V3, and variants; excludes V2.5, L85, PSG-1, and proprietary designs). Engineered for durability and precision in demanding tactical scenarios.\u003c\/p\u003e","brand":"Action Army","offers":[{"title":"Default Title","offer_id":52615147356498,"sku":"A06-003","price":8.07,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/8454\/7507\/files\/11144.jpg?v=1770032265","url":"https:\/\/airsoftmania.eu\/pt-mt\/products\/aa-piano-wire-steel-spring-for-aeg-m120","provider":"Airsoft Mania Europe","version":"1.0","type":"link"}
