The Aero Precision MOD 4 Handguard in 11.4" is a precision-engineered free-float rail built for AR-15 shooters who demand rock-solid accuracy and zero compromises on ergonomics or modularity. Machined from 6061-T6 aluminum with stiffness engineered to minimize deflection under load, this handguard pairs with a steel barrel nut to eliminate point-of-impact shift—especially critical if you're running an IR laser or other precision aiming device. Whether you're building a lightweight carbine, a precision rifle, or anything in between, the MOD 4 delivers the stability that separates good builds from great ones.
Installation is refreshingly straightforward: the barrel nut requires no timing, and its lug pattern matches standard mil-spec castle nuts, so no specialty tools are necessary. The included anti-rotation set screws add redundancy and ensure a tailored fit whether you're using Aero's own M4E1 Threaded Upper Receiver or any mil-spec AR-15 upper. The handguard also plays nice with low-profile gas blocks, giving you real flexibility in your setup.
The 7-sided M-LOK interface runs the full length of the rail, letting you mount lights, grips, bipods, or other accessories exactly where you need them. Four steel-reinforced QD sockets are positioned for fast sling attachment without the premature wear you'd see with standard plastic cups and steel QD points. At just over 15 ounces, the 11.4" length strikes a balance between weight and usable rail real estate—ideal for mid-length builds or those looking to keep a compact footprint without sacrificing mounting options.
This is the kind of mid-tier upgrade that pays dividends in consistency and reliability, and it ships complete with the barrel nut and all necessary hardware.
