Aero 11.4 Mod 4 Handguard Odg

The Aero Precision 11.4 MOD 4 handguard in Odessa Green combines precision engineering with genuine versatility for AR-15 builds that demand accuracy and reliability. Machined from 6061-T6 aluminum, this 11.4-inch rail prioritizes rigidity and minimal deflection under load—critical when you're running optics, lasers, or a mix of accessories that need to stay zeroed. The steel barrel nut is engineered to resist point-of-impact shift even when you're pushing an infrared laser aiming device hard, and the no-timing installation design means you can get it mounted without specialty tools or guesswork.

What sets the MOD 4 apart is thoughtful execution in the details. A 7-sided M-LOK interface runs the full length of the handguard, giving you genuine flexibility to mount lights, foregrips, panels, and other gear exactly where you need them. The four steel-reinforced QD sockets won't wear out when you're rotating heavy sling attachments in and out, and dual anti-rotation set screws lock everything down tight—especially useful if you're running upper receivers from other manufacturers. At 15.06 ounces, it's light enough to keep your rifle balanced without sacrificing the stiffness you need for consistent long-range or tactical shooting.

The MOD 4 handguard ships with the barrel nut and mounting hardware included, and it works seamlessly with Aero's M4E1 Threaded Upper Receivers and PRO series components, as well as any mil-spec AR-15 upper. The 1.2-inch internal diameter clears low-profile gas blocks without any fitment drama, making it ideal for suppressor-ready builds or short-stroke setups.
