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

Aero Precision brings light weight 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 very end of the handguard’s top rail.  No need to guess if one size will be the perfect fit for your barrel.  And 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 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 S-ONE sets the standard for quality across the industry, and it’s all made in the USA.

Atlas Handguard

Got a great deal on the open box S-One and it came to the house brand new. I had a new one I had bought a few months before from another vendor and cannot tell the difference between them.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
