Geissele MK15 Super Modular Rail 14.5" M-LOK Handguard Black

The Geissele MK15 Super Modular Rail transforms AR-15 platforms with precision-machined aluminum construction and M-LOK compatibility. This 14.5-inch handguard delivers the rigidity and modularity that competitive shooters and tactical professionals demand for consistent accuracy and reliable accessory mounting.

What Makes This Different

The MK15 features Geissele's proprietary barrel nut system that creates a true free-float design, eliminating contact pressure that can affect barrel harmonics. Unlike standard handguards that may shift under stress, the MK15's continuous top rail and reinforced mounting points maintain zero even with heavy accessories. The 6061-T6 aluminum construction provides 40% more strength than standard 6063 alloy handguards while weighing just 11.8 ounces.

Key Features

• 14.5-inch length accommodates mid-length and rifle-length gas systems
• M-LOK slots at 3, 6, and 9 o'clock positions for modular accessory mounting
• Continuous Picatinny top rail extends sight radius and optics mounting options
• Anti-rotation tabs prevent handguard movement under recoil stress
• Type III hard coat anodized finish resists corrosion and wear
• Compatible with standard AR-15 upper receivers and gas systems
• Includes proprietary barrel nut and installation hardware

Field testing demonstrates the MK15's ability to maintain consistent point of impact through temperature extremes and high round counts. The rigid platform supports precision shooting applications while the M-LOK system accommodates bipods, lights, and vertical grips without compromising balance. Law enforcement agencies report reliable performance in adverse conditions, with the hard anodized finish showing minimal wear after extended duty use.
