Product DescriptionThe Geissele Super Modular Rail (SMR) MK16 is a premium 15-inch free-float M-LOK handguard designed for AR-15 platforms that demand maximum rigidity and hard-use durability. It mounts using Geissele's proven barrel nut design for straightforward installation and maintenance, while anti-rotation tabs and set screws help keep the rail locked in place under extreme conditions. Precision-machined from strong, lightweight 7000-series aluminum and finished in Type III hardcoat anodizing in Geissele DDC (Desert Dirt Color), the MK16 provides a full-length M1913 Picatinny top rail plus M-LOK slots on every quadrant for flexible accessory placement. Note that DDC may vary in shade from rail to rail, which is intentional for blending in desert environments.Product Highlights 15-inch free-float MK16 Super Modular Rail for AR-15 builds requiring strength, stability, and modularity Full-length M1913 Picatinny top rail with M-LOK attachment slots on all quadrants for extensive customization Anti-rotation tabs and set-screw design helps prevent handguard movement during heavy use Precision-machined 7000-series aluminum construction balances light weight with exceptional rigidity Type III hardcoat anodized Geissele DDC finish; color shade variation is normal and expectedSpecs Brand: Geissele Automatics Model: Super Modular Rail (SMR) MK16 Manufacturer Part Number: 05-792S UPC: 817953028339 Length: 15 in Handguard Type: Free-float Mounting Interface: M-LOK Top Rail: M1913 Picatinny Material: 7000 Series aluminum Finish/Color: Type III hardcoat anodized, Geissele DDC (Desert Dirt Color) Inner Diameter: 1.26 in Outer Diameter: 1.59 in Height: 2.39 in Country of Manufacture: USADisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
