This 13.5-inch rail uses the M-LOK attachment system for streamlined accessory mounting while maintaining a slim profile that improves handling and heat management. The MFR (Modular Float Rail) design eliminates unnecessary bulk while preserving structural rigidity across the full length of the handguard.\u003c\/p\u003e\u003cp\u003eMachined from 6061-T6 aluminum with a hard-anodized black finish, this rail assembly features an uninterrupted top Picatinny rail for optics and backup sights. The M-LOK slots at 3, 6, and 9 o'clock positions allow for direct attachment of lights, grips, and other accessories without adding rail segments. Installation requires a barrel nut wrench (not included) and basic AR-15 armorer tools. Compatible with most mil-spec AR-15 upper receivers.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Free-floating M-LOK handguard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 13.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 platform rifles (mil-spec upper receivers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 6061-T6 aluminum, hard-anodized black finish\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting System:\u003c\/strong\u003e Proprietary barrel nut (included), M-LOK accessory slots\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e Continuous top Picatinny rail, slim profile, heat-dissipating design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Mid-length and carbine-length gas systems; verify clearance with specific barrel and gas block configurations\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Daniel Defense","offers":[{"title":"Default Title","offer_id":47950828863743,"sku":"DD0110715189006","price":348.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/0110715189006b851.jpg?v=1766724777","url":"https:\/\/doublestackstore.com\/products\/mfr-13-5-m-lok-assembly-black","provider":"Double Stack Store","version":"1.0","type":"link"}
