The Timber Creek Outdoors Greyman 10 M-LOK Handguard is a rugged, mid-length rail system designed for the AR-15 platform. Precision-machined from aircraft-grade billet aluminum with a black anodized finish, it features a slim, lightweight design that balances modular flexibility with durability. The system includes a full-length Mil-Spec 1913 Picatinny top rail, integrated QD sling swivel mounting points, a 3-slot accessory rail, and a bi-pod adapter. Like other slim Timber Creek rails, it utilizes a proprietary barrel nut that requires no timing or shims for installation and requires a low-profile gas block for proper clearance. Note: This 10 handguard is backed by a lifetime warranty and is compatible with all standard AR-15 upper receivers.
