Aero Precision APRA500701A Atlas R-One Handguard 7.30" M-LOK, Black Anodized Aluminum, Full Length Picatinny Top, QD Sling Mounts, Mounting Hardware Included for M4E1/AR-15

The Aero Precision Atlas R-One 7.30" M-LOK handguard delivers lightweight performance without sacrificing the rigidity and stability that Aero Precision is known for. Built from 6061-T6 aluminum and finished in black anodize, this M-LOK rail is engineered for shooters who want a slim, minimal-footprint handguard that doesn't compromise strength. The proprietary ATLAS attachment system uses mirrored tapered locking nuts and a turnbuckle screw to distribute clamping pressure evenly across a custom-engineered barrel nut, eliminating the binding and distortion common to conventional designs. A ratcheting detent locks everything in place with positive registration. All mounting hardware is included.

At 5.22 oz, the 7.30" M-LOK profile is a true featherweight choice for any AR build prioritizing mobility and handling. The full-length picatinny rail along the top gives you unlimited mounting flexibility for optics, lights, and other accessories, while quick-disconnect sling mounts at 3, 6, and 9 o'clock positions let you configure your sling attachment exactly how you want it. The 1.5" outer diameter and 1.3" inner bore are compatible with low-profile gas blocks, and the handguard works seamlessly with Aero's M4E1 Threaded Upper Receivers as well as any standard mil-spec AR-15 upper and barrel (though some billet uppers may not work due to indexing tabs).

Whether you're building a lightweight patrol rifle, a dedicated precision trainer, or a fast-handling 3-gun setup, the Atlas R-One delivers Aero's reputation for quality at a weight that won't tire you out over the course of a long day at the range or in the field.
