Overview

Designed for standard AR-15 upper receivers, this handguard is intended for shooters who want a free-float setup with flexible accessory mounting options. Its machined aluminum construction and non-reflective hardcoat anodized finish give it a practical, low-profile look suited to field use and range setups alike. The built-in Picatinny top rail and KeyMod slots at the 3, 6, and 9 o’clock positions provide room for add-on rail segments and accessories, while the included proprietary barrel nut and mounting hardware simplify the installation package. One KeyMod rail segment is included, with additional segments sold separately for users who want to expand the setup.
