Product Description The Aero Precision Atlas R-One Handguard is a 9.30-inch M-LOK handguard precision-machined from 6061-T6 aluminum and finished in a durable black anodized coating. Engineered with size and weight as top priorities, the R-ONE line is the ideal solution for a lightweight AR-15 or M4E1 build. Featuring a full-length Picatinny top rail, integrated QD sling mounts, and Aero Precision&';s proprietary ATLAS (Aero Taper Lock Attachment System), this handguard delivers outstanding strength and stability without unnecessary bulk. The ATLAS system utilizes two mirrored tapered locking nuts that apply evenly distributed clamping pressure across a custom-engineered barrel nut via a turnbuckle screw, while a ratcheting detent ensures positive registration and a secure, distortion-free installation. All mounting hardware is included. The Atlas R-One is designed to seamlessly mate with Aero Precision M4E1 Threaded Upper Receivers and is also compatible with any Mil-Spec AR-15 upper receiver.
