The coating resists carbon fouling and corrosion, allowing the BCG to run cleaner with minimal lubrication through thousands of rounds. The result is smoother cycling, easier cleaning, and outstanding long-term durability.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe lightweight carrier is machined from \u003cstrong\u003e8620 steel\u003c\/strong\u003e, with the bolt and internal components crafted from hardened \u003cstrong\u003esteel\u003c\/strong\u003e. This design achieves a \u003cstrong\u003e21% weight reduction\u003c\/strong\u003e compared to a standard Mil-Spec carrier - the carrier itself weighs just \u003cstrong\u003e6.4 oz\u003c\/strong\u003e, with the complete BCG tipping the scales at only \u003cstrong\u003e9.2 oz\u003c\/strong\u003e. Reducing reciprocating weight translates to faster follow-up shots, decreased bolt bounce, and snappier overall handling. This model ships configured with \u003cstrong\u003eno hammer\u003c\/strong\u003e, making it the ideal match for semi-automatic AR-15 builds.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eFully compatible with all \u003cstrong\u003eMil-Spec AR platforms\u003c\/strong\u003e chambered in \u003cstrong\u003e5.56x45mm NATO\u003c\/strong\u003e (and rated for \u003cstrong\u003e.300 AAC Blackout\u003c\/strong\u003e as well), the Fail Zero Lightweight Bolt Carrier Group is a turn-key upgrade for any build where weight savings, easy maintenance, and proven reliability are top priorities.\u003c\/span\u003e\u003c\/p\u003e","brand":"Fail Zero","offers":[{"title":"Default Title","offer_id":55324447670594,"sku":"FZLWBCG01NH","price":207.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/alt_a1693fb9-cc22-4b09-9b0f-31fc325d09ee.jpg?v=1785151721","url":"https:\/\/centerfiresystems.com\/products\/fail-zero-lightweight-bolt-carrier-group-5-56x45mm-nato-ar-15-no-hammer-exo-nickel-boron","provider":"Centerfire Systems","version":"1.0","type":"link"}
