Geissele MK14 Super Modular Rail 15" M-LOK Handguard

Geissele MK14 Super Modular Rail Handguard

The Geissele MK14 represents the latest evolution in the company's proven Super Modular Rail (SMR) platform. This 15-inch handguard delivers a slimmer profile without sacrificing strength or functionality—a thoughtful design choice for shooters who value both ergonomics and performance.

Construction & Materials

Precision Engineering: The MK14 is machined from 6061-T6 aluminum, selected for its exceptional strength-to-weight ratio. Every component is Type 3 Hardcoat Anodized in Desert Dirt Color for durability and corrosion resistance.

Barrel Nut Design: The included 2.25-inch barrel nut features an extended surface contact area that interfaces directly with the receiver. This design philosophy ensures the free-float rail remains straight and true across its entire length—critical for consistent accuracy.

Modularity & Customization

The MK14 incorporates M-LOK mounting points at the 3, 6, and 9 o'clock positions, giving you full control over your rifle's configuration. Mount lights, bipods, vertical grips, and other accessories exactly where you need them.

Installation

The proven Geissele barrel nut design simplifies installation while delivering superior rigidity. Note: A Geissele barrel nut wrench (sold separately) is required for proper installation.
