The Aero Precision 13.5 Mod 4 handguard is a purpose-built AR-15 rail system engineered to deliver precision, durability, and modularity in one package. Machined from 6061-T6 aluminum and secured with a steel barrel nut, this handguard minimizes optical deflection under load—critical for shooters running mounted optics, lasers, or other accessories that demand rock-solid repeatability. Whether you're running a rifle on the range, in the field, or in a duty role, the MOD 4's rigid construction keeps your zero intact and your point of impact consistent, even under demanding conditions.
The 13.5-inch length strikes a practical balance between ergonomics and rail real estate, giving you ample space to configure your setup without excessive overhang. Installation is straightforward: the barrel nut requires no timing, and its lug pattern matches standard mil-spec castle nuts, so you won't need specialty tools or extra steps. Two anti-rotation set screws provide redundancy and ensure a snug fit, particularly valuable if you're mixing components or cycling handguards across multiple uppers. The steel-reinforced QD sockets are a detail that matters—they're built to handle repeated attachment and detachment of steel sling hardware without wearing soft aluminum.
Customization is core to the MOD 4's appeal. A full-length, 7-sided M-LOK interface runs the entire length of the handguard, giving you flexible mounting points for lights, vertical grips, rail segments, and other tactical or ergonomic accessories. The 1.2-inch internal diameter keeps the handguard low-profile-gas-block compatible, perfect for suppressed builds or setups where you need every inch of real estate. The MOD 4 integrates seamlessly with Aero's M4E1 Threaded Upper Receivers and PRO series components, but it's equally at home on any mil-spec AR-15 upper receiver.

Yes. The 1.2-inch internal diameter is compatible with low-profile gas block designs, making it a good choice for suppressed rifles or builds where gas block profile matters.
The package includes the MOD 4 handguard, the steel barrel nut, and mounting hardware. No additional components are required for installation on a compatible upper receiver.
No. The barrel nut requires no timing and uses a lug pattern that matches standard mil-spec castle nuts, so you can install it with common AR tools and a torque wrench.
