Geissele Automatics HK416 M-LOK Black - Free Float Handguard - 14.5"

The Geissele Automatics HK416 Super Modular Rail is purpose-built for HK416 and MR556 rifles, mounting directly to the standard HK barrel nut so it installs on the HK platform without adapters — a critical distinction from AR-15 handguards that won't mate correctly to the HK barrel geometry.

The Geissele Automatics HK416 Super Modular Rail is a free float handguard from 6061-T6 aluminum with a black Type III hardcoat anodized finish, featuring full-length M-LOK slots at the 3, 6, and 9 o'clock positions, a continuous Picatinny top rail, a 1.35-inch inside diameter, and standard HK barrel nut installation.

M-LOK at 3, 6, and 9 o'clock provides accessory coverage for lights, lasers, and foregrips. The continuous Picatinny top rail delivers full-length optic and accessory mounting. The 1.35-inch inside diameter maintains a slim profile while accommodating standard HK416 gas block configurations, and the 14.5-inch length is optimized for the most common HK416 carbine barrel.
