Atlas S-One 14.94'' Handgrd M-Lok Free Float For Ar-15 Kodiak

The Aero Precision Atlas S-One 14.94" handguard is a lightweight M-LOK free float solution built for AR-15 shooters who refuse to compromise on weight without sacrificing strength. At 7.95 ounces (plus 1.9 oz of mounting hardware), this aluminum handguard delivers the slim profile and rigidity that makes it ideal for precision rifles, hunting builds, and anyone chasing maximum portability. Machined from 6061-T6 aluminum and finished in Kodiak, it's engineered to cut unnecessary mass while maintaining the dependable performance Aero Precision is known for.

The S-One uses Aero's proprietary ATLAS attachment system—a tapered locking design that applies even clamping pressure across the barrel nut to avoid the handguard distortion you sometimes see with other mounting methods. Two mirrored tapered nuts and a turnbuckle screw work together with a ratcheting detent to lock everything in place securely and repeatably. All hardware is included, so you're ready to install out of the box.

At 1.3" inner diameter and 1.5" outer diameter, the S-One accommodates standard low-profile gas blocks and maintains a rail design that won't get in the way. You get full M-LOK slots on the sides and bottom, with indexed grooves at 12 o'clock for repeatable grip control and quick disconnect sling sockets at 3, 6, and 9 o'clock. The front and rear picatinny rails give you flexibility for mounting optics, lights, and other gear without adding bulk.

This is a mil-spec free float handguard that pairs seamlessly with Aero's M4E1 Threaded Upper Receiver or any standard mil-spec AR-15 upper and barrel. It's the choice for builders who want a track record of quality and precision without the weight penalty.
