This drop-in handguard replacement provides multiple attachment points while maintaining a slim profile for improved weapon handling and target acquisition in dynamic shooting scenarios.\u003c\/p\u003e\u003cp\u003eMachined from aircraft-grade aluminum with a hard-anodized black finish, this quad rail is designed for carbine-length gas systems and installs directly onto standard AR-15 barrel nuts using the included delta ring. The full-length top rail co-witnesses with your flat-top upper receiver for uninterrupted mounting options, while integrated heat shield vents help manage barrel heat during extended shooting sessions. No gunsmithing required—installation uses standard armorer's tools.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Drop-in quad rail handguard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, M4 carbine-length gas systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aircraft-grade aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Hard-anodized black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRail System:\u003c\/strong\u003e Four MIL-STD-1913 Picatinny rails\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in replacement, delta ring system included\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Leapers, Inc. - UTG","offers":[{"title":"Default Title","offer_id":47938821980415,"sku":"UTGMTU001","price":59.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1295639.jpg?v=1766532942","url":"https:\/\/doublestackstore.com\/products\/utg-pro-4-15-carb-quad-rail-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
