Slim AR-10 M-LOK Handguard from Aero Precision

The ATLAS R-One isn’t just for your AR-15.  This version of Aero Precision’s new sleek M-LOK handguard with full-length picatinny top rail stands ready for your AR-10 build.  Designed to flow with the design of Aero’s M5E1 receivers, this handguard will work with most Gen 1 DPMS pattern upper receivers with high tang profiles.

These handguards come in 12 and 15 inch long varieties to suit a modern battle rifle build.  Choose from matte black anodizing, or Magpul Flat Dark Earth Cerakote finishes will match with your favorite polymer components, and any Aero Precision M5 receivers.

Innovative Taper Lock Attachment

The ATLAS (Aero Taper Lock Attachment System) gives the handguard its name, and a sleek attachment method.  The ATLAS uses 2 mirrored, tapered locking nuts that evenly distribute clamping force around the barrel nut with a turnbuckle screw.  The handguard also features a ratcheting detent, making the installation secure and preventing distortion during installation.

This handguard includes all the necessary hardware for installation, plus timing shims to provide perfect alignment with your receiver and gas tube.  As with all of Aero Precision’s products, the ATLAS R-ONE sets the standard for quality across the industry, and it’s all made in the USA.
