The Aero Precision MOD 4 handguard is a precision-engineered AR-15 rail system built for shooters who demand rigidity without compromise. This 15-inch M-LOK handguard combines 6061-T6 aluminum construction with a steel barrel nut to minimize point-of-impact shift—especially critical when running infrared lasers or other precision aiming devices under load. Whether you're building a dedicated distance rifle, setting up a duty gun, or customizing a tactical platform, the MOD 4's stiffness and repeatable lockup keep your zero intact when it counts.
Aero Precision designed the MOD 4 around the idea that a rail should be rugged enough to take hard use without needing specialty tools or guesswork during installation. The steel barrel nut requires no timing, and its lug pattern matches standard mil-spec castle nuts—meaning you already own the wrench you need. Two anti-rotation set screws keep everything tight and indexed, even if you swap uppers or use third-party receivers. Steel-reinforced QD sockets at the four hard-mounted positions won't strip or rattle loose when you're slinged up and moving.
The 7-sided M-LOK interface gives you full customization flexibility. Mount lights, covers, backup irons, or rail panels exactly where you need them. The 1.2-inch internal diameter is compatible with low-profile gas blocks, so you won't have to choose between a slim profile and your preferred block design.

Yes. The MOD 4 is designed to work seamlessly with Aero Precision's M4E1 Threaded Upper Receivers and PRO series components. It's also fully compatible with any mil-spec AR-15 upper receiver. The barrel nut lugs match standard mil-spec castle nuts, so installation is straightforward on any compatible platform.
Your purchase includes the MOD 4 handguard itself, the MOD 4 barrel nut, and mounting hardware. No specialty tools are required for installation—your standard castle nut wrench will do the job.
Yes. The MOD 4's 1.2-inch internal diameter is designed to accommodate low-profile gas blocks, so you can maintain a slim profile while keeping your preferred gas block design.
The steel barrel nut is engineered to significantly reduce point-of-impact shift, particularly when running infrared laser aiming devices or other equipment under load. This helps maintain a consistent zero in demanding conditions where deflection would otherwise affect accuracy.
