M5 (.308) Atlas R-One 12.7'' Handguard Mlok For Ar308 Kodiak

The Aero Precision M5 Atlas R-One 12.7" Handguard with M-LOK is built for shooters who demand a lightweight, rigid platform on their .308 AR build without sacrificing strength or modularity. This slim-profile aluminum handguard uses Aero's proprietary ATLAS (Aero Taper Lock Attachment System) to deliver the stability and repeatability you expect from Aero Precision, while keeping weight down for faster, more responsive handling—ideal whether you're running a precision rifle, hunting platform, or competition gun.

Machined from 6061-T6 aluminum, the R-One line was engineered with size and weight in mind. At just 8.79 oz, this 12.7" handguard is lean enough for a lightweight build without cutting corners on durability. The ATLAS system uses mirrored tapered locking nuts and a custom barrel nut with a turnbuckle screw to apply even clamping pressure—a design that avoids the distortion some shooters see with other mounting methods. A ratcheting detent adds a final layer of positive registration and security.

The R-One ships with all necessary mounting hardware included and is fully compatible with standard AR308 upper receivers and barrels. It features a full-length top picatinny rail for mounting optics or accessories, M-LOK slots for tactical attachments, and quick-disconnect sling sockets at 3, 6, and 9 o'clock positions. The 1.3" inside diameter accommodates standard .308 barrels, and the handguard plays well with low-profile gas blocks—a practical detail for shooters building compact setups.

One important note: these handguards do not include an armorer's wrench, though any standard armorer's wrench will work with M5 ATLAS models. Also, they are designed for standard M5 receivers; billet upper receivers may have indexing issues due to the handguard's design tabs.
