Geissele Automatics MK4 Free Float AR-15 Handguard - M-LOK - 10.5" - DDC

The Geissele MK4 Super Modular Handguard solves the strength-and-modularity trade-off of standard AR-15 rails, pairing a proprietary barrel nut with extensive venting to keep the rifle light and cool. Built for shooters who want a rigid, accurate platform, this 10.5" version adds M-LOK slots at multiple angles for versatile accessory mounting.

Features:

• 10.5" free-float handguard for AR-15 platforms
• M-LOK slots at 3, 6, 9 o'clock and upper 45°
• Integrated Picatinny sections at the front
• Proprietary 2.25" barrel nut
• 7000-series aluminum construction
• DDC Type III hardcoat anodize
• 1.35" inner diameter, 2.11" outer diameter
• 10.6 oz weight (12.74 oz with barrel nut)

Integrated Picatinny rail sections at the 3, 6, and 9 o'clock positions sit up front for accessory mounting, while M-LOK slots at those same positions and the upper 45-degree angles add further attachment points. Geissele's 2.25" barrel nut creates a strong, secure link to the upper receiver for a rigid, accurate platform, and extensive venting keeps the rail's weight down while helping the barrel run cooler. At 10.6 ounces bare (12.74 ounces with the barrel nut installed), it adds only modest weight for the rigidity and accessory space it provides. Note: Geissele's Desert Dirt Color (DDC) finish refers to a variety of shades of desert terrain designed to better break up a rifle's outline. These colors can vary drastically even between products from the same batch and are not intended to color match. Per Geissele Automatics, the only way to receive a uniform color across all parts and accessories is to have them refinished with a coating such as DuraCoat or Cerakote.

Founded in 2004 by Bill Geissele in Pennsylvania, Geissele Automatics built its reputation on precision AR-15 triggers before expanding into rail systems and other combat-proven components. The company's Super Modular Rail line has been adopted by U.S. Special Operations Command, reflecting the same engineering rigor Geissele applies across its entire product line.
