This 15.25-inch rail replaces factory handguards to provide a full-length M-LOK attachment platform, improved heat dissipation, and a slim profile that enhances handling without adding unnecessary bulk. Ideal for shooters building a versatile carbine or upgrading an existing rifle for better accessory mounting and thermal management.\u003c\/p\u003e\u003cp\u003eMachined from 6061-T6 aluminum with a black Type III hard-anodized finish, the L89 Rail features M-LOK slots at the 3, 6, and 9 o'clock positions and a continuous Picatinny top rail for optics and backup sights. Installation requires a barrel nut wrench and armorer's wrench; the rail uses a proprietary barrel nut system. While mechanically inclined shooters can perform the installation, professional fitting is recommended to ensure proper alignment and torque specs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Free-Float Handguard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 (mid-length and rifle-length gas systems)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061-T6 Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Type III Hard Anodized Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 15.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment System:\u003c\/strong\u003e M-LOK (3, 6, 9 o'clock), Picatinny top rail\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Professional Recommended (requires barrel nut wrench and proper torque)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Handguard, proprietary barrel nut, mounting hardware\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sons of Liberty Gun Works","offers":[{"title":"Default Title","offer_id":48405704114431,"sku":"SOLGWRAIL-L89-S-1525","price":389.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5811878.jpg?v=1776441023","url":"https:\/\/doublestackstore.com\/products\/solgw-l89-rail-15-25-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
