The O-rings provide a more rigid option for biasing the hop-up assembly towards the gearbox, ensuring the hop-up will not move away from the nozzle tip during use. This is a common method for stabilizing the hop-up, and works well with other HPA systems, as well as AEG systems.\u003c\/span\u003e\u003c\/p\u003e","brand":"PolarStar","offers":[{"title":"Default Title","offer_id":53271294705888,"sku":"10001468","price":2.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0023\/7466\/4301\/files\/10Photoroom_20260218_133414.webp?v=1771442624","url":"https:\/\/polarstarairsoft.com\/products\/barrel-shim-o-rings-10pk","provider":"PolarStar","version":"1.0","type":"link"}
