Built from aircraft-grade 6061-T6 aluminum and finished with a Mil-Spec Type III hard coat anodizing, this two-piece rail delivers a strong, stable mounting platform while helping improve accuracy through its free-floating barrel design. The RIS II’s innovative two-piece construction allows an M203 grenade launcher to be attached when the lower rail section is removed—without the need for special tools—by integrating the required components directly into the rail. It also features an uninterrupted top rail and Mil-Std 1913 Picatinny rails for consistent alignment and broad accessory compatibility. This system is intended to be used in conjunction with the MK12 Low Profile Gas Block.\u003c\/p\u003e\u003ch3\u003eProduct Highlights\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFree-floating barrel design helps maximize accuracy and consistency\u003c\/li\u003e\n\u003cli\u003eTwo-piece USSOCOM-inspired design supports M203 mounting when lower rail is removed (no special tools required)\u003c\/li\u003e\n\u003cli\u003eBattle-tested 6-bolt Bolt-Up System securely mates the handguard to the upper receiver\u003c\/li\u003e\n\u003cli\u003eUninterrupted upper rail with Mil-Std 1913 Picatinny rails for optics and accessory mounting\u003c\/li\u003e\n\u003cli\u003eAircraft-grade 6061-T6 aluminum construction with Mil-Spec Type III hard coat anodized finish (Black)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Daniel Defense\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Rail Interface System \/ Handguard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e RIS II M4A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\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 Mil-Spec Type III Hard Coat Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Two-piece\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Float:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Upper Rail:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRail Standard:\u003c\/strong\u003e Mil-Std 1913 Picatinny\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment System:\u003c\/strong\u003e 6-bolt Bolt-Up System; Grade 8 military specification fasteners\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas System Compatibility:\u003c\/strong\u003e Carbine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarrel Nut:\u003c\/strong\u003e Steel (for patented Bolt-Up System)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRail Length:\u003c\/strong\u003e 12.25 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 2.23 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 2.25 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter:\u003c\/strong\u003e 1.15 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 17.7 oz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 01-004-08001-006\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 852548002561\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
