Atlas S-One 10.3'' Handgrd M-Lok Free Float For Ar-15 Kodiak

The Aero Precision Atlas S-One 10.3'' handguard with M-LOK is built for shooters who refuse to compromise between control and weight on their AR-15. Machined from 6061-T6 aluminum, this free-float handguard uses Aero's proprietary ATLAS (Aero Taper Lock Attachment System) to deliver rock-solid stability without the bulk. At just 6.0 ounces, the 10.3'' option strikes the balance serious builders need for lightweight setups, tactical builds, and hunting rifles where every ounce matters.

The ATLAS system is engineered to distribute clamping pressure evenly across the receiver using mirrored tapered locking nuts and a turnbuckle screw, preventing the handguard distortion that plagues other designs during installation. A ratcheting detent locks everything in place with positive registration, so your rail stays true. All mounting hardware is included—no hunting for parts. The slim profile and indexed 12 o'clock positioning grooves give you a secure, intuitive grip; QD sling sockets at 3, 6, and 9 o'clock let you configure your setup the way you want it. Front and rear picatinny rails accommodate optics and accessories, while the eliminated center top rail keeps weight down without sacrificing mounting real estate. The 1.3'' inner diameter and 1.5'' outer diameter are compatible with low-profile gas blocks, so your build stays compact.

This handguard works seamlessly with mil-spec AR-15 upper receivers and barrels. Note: it is not compatible with Aero's M4E1 Enhanced Upper Receiver due to indexing tabs. Whether you're building a lightweight hunting rifle, a competition gun, or a general-purpose AR, the Atlas S-One delivers the precision and durability Aero Precision is known for—without the excess weight or installation headaches.
