Aero Enhanced AR-15 Handguard with Wide Inside Diameter

The Aero Enhanced M-LOK Handguard comes packed with features, and unique benefits for serious shooters. This handguard features a 1.72″ internal diameter, allowing you to bury a suppressor below the length if you so choose. Fully modular with M-LOK slots at the 3, 6, and 9 o’clock positions, plus a full length picatinny top rail and QD sling sockets as well.

For shooters running laser aiming modules, this handguard is also great at reducing deflection and zero shift when paired with an Enhanced M4E1 upper. The handguard mounts directly to the upper’s unique forging, and is held in place with 8 screws, rather than attaching to a barrel nut. By separating the barrel from the handguard, less stress is placed on the barrel nut for improved accuracy and less zero shift.

Can I use this with a regular AR-15 receiver?

Yes you can! By purchasing a separate Aero Precision BAR barrel nut, you can mount an enhanced handguard on a more standard forged upper receiver. We do recommend an Enhanced Aero Upper for best results though. For those hoping to run a little lighter and slicker, there is now a Slick Side Enhanced Upper.
