Made from CNC‑machined POM for precision and durability, this piston head is designed for players who want smoother cycling and tighter FPS consistency.\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe \u003cstrong\u003efront ventilation ports\u003c\/strong\u003e expand the O‑ring during each shot, ensuring that all air inside the cylinder is pushed forward to propel the BB — maximising efficiency and stabilising FPS. The \u003cstrong\u003edouble O‑ring setup\u003c\/strong\u003e further enhances sealing performance, especially in upgraded builds.\u003cbr\u003e\u003cbr\u003eThe integrated \u003cstrong\u003eball‑bearing system\u003c\/strong\u003e reduces spring tension during compression and release, helping maintain spring health and improving gearbox smoothness. When paired with a ball‑bearing spring guide, it forms an optimal low‑stress setup.\u003cbr\u003e\u003cbr\u003eA key feature of the TPAA is its \u003cstrong\u003eadjustable AOE system\u003c\/strong\u003e, allowing you to fine‑tune piston length by \u003cstrong\u003e1, 2, 3 or 4 mm\u003c\/strong\u003e, or run it without shims. Perfect AOE dramatically improves gearbox reliability and reduces impact stress.\u003cbr\u003e\u003cbr\u003eAs an air‑brake piston head, the TPAA also \u003cstrong\u003ereduces gearbox noise\u003c\/strong\u003e by creating an air cushion at the end of the piston stroke — ideal for players who want a quieter, smoother‑running build.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 10.89 g\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e CNC POM\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e Double O‑ring, ball bearings, adjustable AOE (1–4 mm), air‑brake design\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e 100% Marui‑spec AEGs\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eOrigin:\u003c\/strong\u003e 100% Made in Italy","brand":"FPS Softair Italy","offers":[{"title":"Default Title","offer_id":58711535092043,"sku":"TPAA","price":13.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/3362\/5931\/files\/FPS_airbrake_pistonhead_TPAA_1.jpg?v=1791199301","url":"https:\/\/outdoorzone.ie\/products\/fps-air-brake-cnc-pom-double-o-ring-ball-bearing-aeg-piston-head-with-adjustable-aoe","provider":"Outdoor Zone Ireland","version":"1.0","type":"link"}
