M-LOK AR-15 Handguard – Flat Dark Earth – 15″: Lightweight Precision for Tactical Builds

This 15″ M-LOK handguard delivers a rigid, ergonomic platform for AR-15 builds without unnecessary bulk. Machined from 6061-T6 aluminum with a Type III hardcoat anodized finish, it withstands recoil and field use while keeping weight under 12oz. The Flat Dark Earth (FDE) Cerakote option provides corrosion resistance and low-profile camouflage. Compatible with most mil-spec AR-15 upper receivers.

Key Specifications

• Material: 6061-T6 aluminum with Type III hardcoat anodizing
• Finish: Cerakote Flat Dark Earth (FDE)
• Length: 15″ (measured from receiver face)
• Weight: 11.8 oz
• Attachment System: M-LOK slots at 1:30, 3:00, 4:30, 6:00, 7:30, 9:00, 10:30 positions
• Inner Diameter: 1.5″ (clears most suppressor mounts)

Feature Breakdown

The handguard’s monolithic top rail maintains zero for optics and backup sights, while the M-LOK system allows tool-free accessory mounting. Eight M-LOK slots per side provide flexibility for lights, grips, or bipods without adding width. The slim profile (1.75″ outer diameter) improves handling compared to bulky quad-rail designs.

Heat mitigation comes from the integrated heat shield and ample venting along the sides. The 6061-T6 aluminum construction dissipates heat faster than polymer alternatives, reducing mirage effect during sustained fire. Anodizing prevents galling and wear at contact points with the barrel nut.

Installation requires only a standard armorer’s wrench for the barrel nut and hex keys for the included hardware. The anti-rotation system uses positive engagement with the upper receiver, eliminating the need for timing shims. All necessary mounting screws and indexing components ship pre-greased.

Cerakote FDE matches common tactical finishes while providing superior abrasion resistance to spray paint. The coating undergoes 500-hour salt spray testing to prevent corrosion in humid environments. Unlike cheaper coatings, it won’t chip during routine cleaning with solvents.

Compatibility Notes

• Fits standard AR-15/M4 platforms with mil-spec upper receivers
• Requires proprietary barrel nut (included)
• Clears low-profile gas blocks (0.75″ max height under rail)
• Not compatible with piston-driven uppers without modification

Installation Overview

Remove existing handguard and barrel nut. Install the included barrel nut using 35 ft-lbs torque, aligning the notches with the gas tube channel. Slide the handguard onto the nut and secure with four hex screws at 12 in-lbs. Verify anti-rotation tabs engage the receiver before final tightening.

Frequently Asked Questions

Q: Does this work with a carbine-length gas system?
A: Yes, the 15″ length covers mid-length and rifle-length gas systems while leaving carbine-length blocks exposed.

Q: Will a 0.750″ gas block fit underneath?
A: All low-profile blocks under 0.75″ height clear the interior. Measure block height if using non-standard sizes.

Q: Is the Cerakote applied over anodizing?
A: Yes, the aluminum is hardcoat anodized before Cerakote application for maximum adhesion and corrosion protection.

Q: What’s the torque spec for M-LOK accessories?
A: Use 15-20 in-lbs on M-LOK bolts. Over-tightening can deform the slots.

Q: Does this include a wrench for the barrel nut?
A> No, a standard armorer’s wrench is required but not included due to variations in wrench designs.

Warranty & Shipping

Lifetime warranty against manufacturing defects. Cerakote finish covered for one year against peeling or bubbling under normal use. Ships via USPS Priority or UPS Ground within 2 business days. No signature required for delivery.
