• Inner Diameter: Accommodates most low-profile gas blocks
• Barrel Compatibility: Works with carbine, mid-length, or rifle-length gas systems

Feature Breakdown

The handguard’s 6061-T6 aluminum construction ensures impact resistance while keeping weight manageable during extended use. The Type III hardcoat anodizing provides corrosion protection without adding thickness that could interfere with accessory fitment. Unlike polymer alternatives, this rail maintains zero under recoil and won’t flex under pressure from bipods or angled grips.

M-LOK slots offer tool-free attachment for lights, lasers, and vertical grips without the bulk of Picatinny rails. The 15″ length provides ample real estate for accessories while leaving room for muzzle devices. Anti-rotation tabs and a secure barrel nut interface prevent movement during rapid fire or rough handling.

A continuous top rail ensures seamless optic alignment with your receiver, while the slim profile improves grip ergonomics. The FDE finish reduces glare in bright conditions and blends with common tactical gear. Internal machining minimizes sharp edges that could snag during deployment.

Heat dissipation is optimized through the open design, preventing excessive buildup during sustained fire. The handguard’s ID clears most aftermarket gas blocks, though users should verify clearance with their specific setup. No proprietary tools are required for installation—standard AR armorer’s wrenches suffice.

Compatibility

Fits most mil-spec AR-15 upper receivers with a threaded barrel nut. Compatible with carbine, mid-length, and rifle-length gas systems when paired with appropriate low-profile blocks. Not designed for use with piston-driven uppers or non-standard receiver extensions. Check your barrel nut thread pattern (typically 1.375″-24TPI) before purchase.

Installation Overview

Remove existing handguard and muzzle device (if necessary). Secure the included barrel nut using a reaction rod or upper vise block, torquing to manufacturer specifications. Slide the handguard onto the nut and align anti-rotation tabs with the receiver. Secure with provided screws, alternating tightening to ensure even pressure. Reinstall gas tube and test function before live fire.
