Constructed from 6061-T6 aluminum and finished with a Type III hard coat anodize, the handguard ships with a 4140 heat-treated barrel nut, wrench, and torque plate plus a 5-slot polymer M-LOK rail section. Designed and manufactured in the United States, it focuses on fit, finish, and compatibility while remaining a straightforward functional upgrade for modern AR builds.
