{"product_id":"luth-ar-bolt-gas-rings-3-pack","title":"Luth-AR Bolt Gas Rings (3-Pack) – AR-15\/M16 Bolt Carrier Group Replacement","description":"\u003cp\u003eGas rings seal the gap between your bolt and carrier, preventing gas loss during the firing cycle. When worn or damaged, they cause short stroking, failure to cycle, and excessive carbon fouling in the carrier. This 3-pack from Luth-AR provides replacement rings to restore proper gas seal and reliable function in your AR-15 or M16 bolt carrier group.\u003c\/p\u003e\u003cp\u003eMachined from heat-treated steel with a corrosion-resistant finish. Installation requires disassembly of the bolt from the carrier—rings fit into the machined grooves on the bolt body. Stack the three rings with staggered gaps (not aligned) to maintain proper seal. Basic armorer tools and knowledge of BCG disassembly required. Keep spares on hand for routine maintenance or emergency field repairs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Bolt Gas Rings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, M16 Bolt Carrier Groups\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-Treated Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Corrosion-Resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (Requires BCG Disassembly)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e 3 Gas Rings\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Luth-AR","offers":[{"title":"Default Title","offer_id":47938434138367,"sku":"LUTHBT-01-3P","price":3.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1290138.jpg?v=1766514942","url":"https:\/\/doublestackstore.com\/products\/luth-ar-bolt-gas-rings-3-pack","provider":"Double Stack Store","version":"1.0","type":"link"}
