It features extensive venting for heat dissipation and reduced overall weight, plus integrated M1913 Picatinny rail sections at the fore end in the 3, 6, and 9 o’clock positions for streamlined accessory placement. M-LOK slots are provided at the 3, 6, and 9 o’clock positions as well as the upper 45-degree quadrants for highly modular setup options. The MK4 includes Geissele’s proprietary 2.25-inch long barrel nut to increase surface contact with the receiver for a straight, true rail that supports accuracy and repeatable zero after maintenance and reassembly. Barrel nut is included; a Geissele barrel nut wrench is required for installation and is sold separately.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eUltra-lightweight, free-float MK4 handguard designed for a strong and rigid AR-15 rail platform\u003c\/li\u003e\n  \u003cli\u003eM-LOK mounting interface at 3\/6\/9 o’clock plus upper 45-degree quadrants for versatile accessory placement\u003c\/li\u003e\n  \u003cli\u003eIntegrated short M1913 Picatinny rail sections at the front (3, 6, and 9 o’clock) for compact mounting points\u003c\/li\u003e\n  \u003cli\u003eMaximum venting improves heat dissipation while reducing overall handguard weight\u003c\/li\u003e\n  \u003cli\u003eIncludes Geissele proprietary 2.25-inch barrel nut for improved rigidity and repeatable alignment (wrench sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Geissele Automatics\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct:\u003c\/strong\u003e Super Modular Rail (SMR) MK4 M-LOK handguard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 9.3 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 2.4 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter:\u003c\/strong\u003e 1.35 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter:\u003c\/strong\u003e 2.11 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight (with hardware):\u003c\/strong\u003e 11.2 oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRail Sections:\u003c\/strong\u003e Integrated short M1913 Picatinny sections at fore (3\/6\/9 o’clock)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Interface:\u003c\/strong\u003e M-LOK (3\/6\/9 o’clock and upper 45-degree quadrants)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e Barrel nut (barrel nut wrench sold separately)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 05-283S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 854014005700\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\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.
