Aero Precision Atlas S-One M-LOK Handguard



Slick Top M-LOK Handguard – Aero Precision ATLAS S-ONE

Aero Precision brings lightweight and usability to the table with the ATLAS S-ONE M-LOK handguard. This handguard features a smooth top rail for an optimal c-clamp grip, M-LOK slots at the 3, 6, and 9 o’clock positions, with 3 sling swivel sockets, and room for a backup iron sight at the front. This handguard is easy to handle and looks perfect with Aero’s M4E1 or EPC-9 upper receivers.

The various lengths available are the actual length, measured from where the handguard meets the top of your upper receiver to the end of the handguard’s top rail—no need to guess if one size will be the perfect fit for your barrel.  You can color match with Magpul Flat Dark Earth, OD Green, Sniper Grey, and Burnt Bronze Cerakote options.

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 the clamping force around the barrel nut with a turnbuckle screw.  The handguard also features a ratcheting detent, securing the installation 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 S-ONE sets the standard for quality across the industry, and it’s all made in the USA.
