Geissele Super Modular Rail MK16 M-LOK - Free Float Handguard - 15"

The Geissele Super Modular Rail MK16 at 15 inches gives AR-15 builds running a full-length or mid-length configuration one of the most rigid free float rails available at this price point. Built for shooters who run dedicated optics and accessories that must hold zero under sustained use, this handguard provides Geissele's signature barrel nut rigidity across a 15-inch span.

The MK16 is a 15-inch free-floating AR-15 handguard designed for shooters who require maximum rail coverage with proven lockup rigidity and full M-LOK accessory compatibility.

Geissele's barrel nut design, paired with anti-rotation tabs and set screws, prevents rail movement even under the most extreme use conditions. M-LOK slots at every quadrant deliver maximum accessory placement options, and the full-length M1913 Picatinny top rail supports optics, magnifiers, and night vision devices across the full rail length. Aircraft-grade 7000 series aluminum construction keeps the handguard stiff and light across its longer span.

Compatible with all mil-spec AR-15 uppers and installs using Geissele's proven barrel nut system. The 15-inch length suits rifle-length and mid-length gas system configurations.

Machined from 7000 series aluminum with a Mil-Spec Type III hardcoat anodized finish for superior hardness and corrosion resistance compared to standard anodizing.

This handguard performs on precision carbines, competition rifles, and duty AR-15s where a long, rigid free float rail provides the stability needed for accurate, repeatable shooting.

Geissele Automatics has been supplying military units and competitive shooters with precision AR components since 2004.
