If you’re looking for a KeyMod free float handguard, but you’re a little hesitant because so many of them are distorted after installation we’re ready to set your mind at ease. Wing Tactical brings you the Aero Precision ATLAS KeyMod Handguard, a feature packed KeyMod handguard that won’t distort because it attaches with Aero’s new proprietary ATLAS mounting system.

What is ATLAS?

ATLAS is the proprietary mounting system used on the latest generation of Aero Handguards. The Aero Taper Lock Attachment System is a breath of fresh air in the attachment of free floated handguards. While other attachment methods can torque a handguard out of shape, the new Aero Handguard ATLAS system uses a turnbuckle screw to create an even distribution of pressure across a specialized barrel nut. That special nut and screw setup teams up with a ratcheting detent that gives your handguard added security. That solid mount with equalized pressure gives you a secure handguard that remains true, with no distortion, after installation.

The Aero Precision ATLAS S-ONE KeyMod Handguard is Low Profile With Big Features

This is the low profile KeyMod free float handguard you’ve been waiting for. It’s lightweight and easy to grasp, yet affords enough space in its inner diameter that low profile gas blocks clear nicely. The 12 o’clock area of this handguard features a series of ridges that offer extra purchase with incredible grasping comfort. Advanced KeyMod mounting rails offer the operator the option of equipping accessories without having to remove the forend. Use any KeyMod accessory you like and adapt Picatinny components with available adapter plates. Comfort, light weight, flexibility, and good looks make this Aero handguard an easy choice for your next build.
