Over time those rings can stick, gap unevenly, or wear out, leading to gas leaks, short cycling, or fouling in the receiver. The Luth-AR BT-01H's \u003cstrong\u003esingle-piece helical design\u003c\/strong\u003e eliminates ring alignment issues, holds even tension against the gas tube wall, and installs in seconds on any standard \u003cstrong\u003eAR-15 bolt\u003c\/strong\u003e. The \u003cstrong\u003esilver\u003c\/strong\u003e finish is a natural all-metal appearance.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eWhether you are assembling a new AR-15 upper, refreshing a duty bolt, or troubleshooting cycling issues, the BT-01H offers a straightforward drop-in upgrade. \u003cstrong\u003eOne gas ring is included.\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Luth-AR","offers":[{"title":"Default Title","offer_id":55101258432834,"sku":"186447","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_a53b8763-1e87-474a-bc50-2b3e625baac6.png?v=1784791524","url":"https:\/\/centerfiresystems.com\/products\/luth-ar-bt-01h-helical-1-piece-gas-ring-223-5-56-silver-ar-15","provider":"Centerfire Systems","version":"1.0","type":"link"}
