Its inner diameter is engineered at ?6.03 mm with a precision tolerance of ?0.01 mm, offering a tighter bore than the Tokyo Marui original specification of ?6.08 mm. The barrel length is designed to improve airtightness, while its enhanced stainless steel construction supports solid BB stability and accuracy. This barrel is compatible with the GBB M4A1 MWS (Tokyo Marui) and GBB TYPE89 (Tokyo Marui). As with any custom upgrade, users should check the muzzle velocity of the airsoft replica after installation and follow the legislation of their own country as well as local field rules.\u003cbr\u003e\u003cbr\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul style='margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px !important; margin-left: 0px; padding-left: 18px; color: rgb(15, 17, 21); font-family: quote-cjk-patch, Inter, system-ui, -apple-system, BlinkMacSystemFont, \"Segoe UI\", Roboto, Oxygen, Ubuntu, Cantarell, \"Open Sans\", \"Helvetica Neue\", sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;'\u003e\n\u003cli\u003e\u003cp class=\"ds-markdown-paragraph\" style=\"margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;\"\u003e\u003cspan class=\"\"\u003eFirst Factory 6.03mm inner barrel for Tokyo Marui MWS \/ Type 89 GBB, 250mm length\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli style=\"margin-top: 6px;\"\u003e\u003cp class=\"ds-markdown-paragraph\" style=\"margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;\"\u003e\u003cspan class=\"\"\u003eInner diameter designed at ?6.03mm with precision tolerance of ?0.01mm\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli style=\"margin-top: 6px;\"\u003e\u003cp class=\"ds-markdown-paragraph\" style=\"margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;\"\u003e\u003cspan class=\"\"\u003eTighter bore than Tokyo Marui original ?6.08mm\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli style=\"margin-top: 6px;\"\u003e\u003cp class=\"ds-markdown-paragraph\" style=\"margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;\"\u003e\u003cspan class=\"\"\u003eLength designed to improve airtightness\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli style=\"margin-top: 6px;\"\u003e\u003cp class=\"ds-markdown-paragraph\" style=\"margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;\"\u003e\u003cspan class=\"\"\u003eMade with enhanced stainless steel material for solid BB stability and accuracy\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli style=\"margin-top: 6px;\"\u003e\u003cp class=\"ds-markdown-paragraph\" style=\"margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;\"\u003e\u003cspan class=\"\"\u003eCompatible with GBB M4A1 MWS (Tokyo Marui)\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli style=\"margin-top: 6px;\"\u003e\u003cp class=\"ds-markdown-paragraph\" style=\"margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;\"\u003e\u003cspan class=\"\"\u003eCompatible with GBB TYPE89 (Tokyo Marui)\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli style=\"margin-top: 6px;\"\u003e\u003cp class=\"ds-markdown-paragraph\" style=\"margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;\"\u003e\u003cspan class=\"\"\u003eCheck the muzzle velocity of the airsoft replica after custom upgrades\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli style=\"margin-top: 6px;\"\u003e\u003cp class=\"ds-markdown-paragraph\" style=\"margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;\"\u003e\u003cspan class=\"\"\u003eFollow the legislation of your own country\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003cli style=\"margin-top: 6px;\"\u003e\u003cp class=\"ds-markdown-paragraph\" style=\"margin-top: 0px !important; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;\"\u003e\u003cspan class=\"\"\u003eFollow local field rules\u003c\/span\u003e\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e","brand":"First Factory (Laylax)","offers":[{"title":"Default Title","offer_id":67728113762532,"sku":"FF-4571443137715","price":40.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/1325\/2580\/files\/FF-4571443137715-2e.jpg?v=1792642608","url":"https:\/\/www.ehobbyasia.com\/products\/first-factory-6-03mm-inner-barrel-for-tokyo-marui-mws-type-89-gbb-250mm","provider":"eHobbyAsia","version":"1.0","type":"link"}
