This BCG features integrated side charging capability, allowing shooters to charge the rifle from the side without using a traditional charging handle—useful for left-handed shooters, suppressed shooting, or when using low-profile optics that interfere with standard charging handle manipulation. The enhanced design maintains compatibility with mil-spec upper receivers while offering improved ergonomics and operational flexibility.\u003c\/p\u003e\u003cp\u003eConstructed from 8620 steel with a nickel boron (NiB) coating, this BCG delivers exceptional durability and low-friction performance. The nickel boron finish reduces friction, enhances corrosion resistance, and simplifies cleaning compared to traditional phosphate or chrome-lined carriers. Installation is drop-in for experienced AR builders familiar with BCG replacement; ensure proper headspacing and function testing after installation. The side charging feature requires an upper receiver with side charging port or compatible modification.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Enhanced Bolt Carrier Group with Side Charging\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 pattern rifles in 5.56 NATO\/.223 Remington\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 8620 Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Nickel Boron (NiB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (experienced builders; requires upper with side charging capability)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Bolt carrier, bolt assembly, cam pin, firing pin, firing pin retaining pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LanTac USA LLC","offers":[{"title":"Default Title","offer_id":48405651030271,"sku":"LAN01-UP-SC-NIT-EBCG","price":269.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5811522.jpg?v=1776439655","url":"https:\/\/doublestackstore.com\/products\/lantac-e-bcg-556-side-charge-nib-1","provider":"Double Stack Store","version":"1.0","type":"link"}
