Designed for players and technicians seeking reliable performance under high spring pressures, it pairs precision engineering with practical gearing benefits.\u003c\/p\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eMaterial\u003c\/b\u003e: Dural aluminium (Dural EN-AW 7075-T6) for exceptional strength-to-weight balance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCoating\u003c\/b\u003e: PTFE (Teflon) coating reduces friction inside the cylinder, promoting smoother cycling and longer component life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eVentilation\u003c\/b\u003e: 11 vent holes that prevent air lock during cycling, aiding consistent compression and operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSeals\u003c\/b\u003e: Double O-ring seal to minimize air loss and keep the piston perfectly aligned within the cylinder.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBearing\u003c\/b\u003e: Ball bearing attached to rotate with the spring, helping to resist deformation under pressure and maintain tuning stability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCompatibility\u003c\/b\u003e: Safe for use with up to M140 springs, making it suitable for high-torque builds while maintaining reliability.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eBenefits: With aerospace-grade materials and a PTFE coating, this piston head reduces friction, lowers wear, and preserves cylinder integrity under heavy spring pressures. The 11 vent holes mitigate vacuum effects during firing, while the dual O-rings and rotating ball bearing maintain a stable, airtight seal and consistent alignment. Together, these features translate to smoother operation, steadier FPS, and improved durability for upgraded AEG setups that push toward high-torque performance.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Socom Tactical Airsoft","offers":[{"title":"Default Title","offer_id":56494943961413,"sku":"E310-AL","price":16.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0948\/3767\/0213\/files\/epes-aeg-piston-head-dural-h-ptfe-9958135.jpg?v=1764961634","url":"https:\/\/www.longshottactical.co.uk\/products\/epes-aeg-piston-head-dural-h-ptfe","provider":"Longshot Tactical","version":"1.0","type":"link"}
