The Aero Precision 9.1 Mod 4 Handguard brings practical design and solid engineering to your AR-15 or M4 build. At 9.1 inches, this mid-length handguard strikes a clean balance between sight radius and hand placement, making it a natural fit for hunters, precision shooters, and builders who value both function and weight consciousness. Machined from 6061-T6 aluminum and finished in Kodiak Brown, it delivers durability without unnecessary heft—at just 5.27 ounces, every gram counts when you're carrying your rifle into the field or to the range.
Built for mil-spec AR-15 and M4E1 upper receivers, the Mod 4 uses an M-LOK mounting system that's become the standard for modern rifle accessory placement. The eliminated center-top rail keeps weight low while the indexed grooves at the 12 o'clock position give your grip a consistent, positive reference point. Quick-disconnect sling mounts at 3, 6, and 9 o'clock mean you can run your sling setup however makes sense for your mission. The 1.3-inch inside diameter accommodates low-profile gas blocks without fuss, and the 1.5-inch outer diameter keeps the profile lean.
If you're building around Aero's own M4E1 Upper Receiver or PRO Series components, the Mod 4 handguard drops in seamlessly—both in fit and aesthetics. It's the kind of upgrade that doesn't demand attention; it just works. Whether you're assembling a hunting rifle, a 3-gun build, or a precision AR, this handguard gets out of your way and lets you focus on shooting.
