This Prometheus EG inner barrel builds on the proven barrel design of Tokyo Marui. With an inner diameter of 6.03 mm and particularly tight tolerances (+\/- 0.01 mm), quality BBs get a neat fit in the barrel. The result: minimal pressure loss, even sealing around the BB and therefore accurate shot grouping. The outer diameter is 8.5 mm.\u003c\/p\u003e\n\u003cp\u003eFor the construction, sturdy, high-quality stainless steel was chosen. This causes this barrel to deform much slower than a standard one and can handle a lot. Among shooters, a Prometheus inner barrel is a trusted choice, with gains on multiple fronts:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMore accurate\u003c\/li\u003e\n\u003cli\u003eMore robust\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Prometheus","offers":[{"title":"Default Title","offer_id":57782175826252,"sku":"361815448","price":55.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0813\/3430\/5100\/files\/inner_barrel_prometheus_eg_g_g_arp9arp556_1.jpg?v=1781323508","url":"https:\/\/www.tacticaltrophy.com\/products\/inner-barrel-prometheus-eg-g-g-arp9-arp556","provider":"Tactical Trophy","version":"1.0","type":"link"}
