Constructed from 100% aluminum and hardcoat anodized for a durable, anti-reflective finish, this handguard features a unique mounting, indexing and locking system that prevents rail movement under heat generated from the barrel nut. It also has KeyMod mounting slots on seven sides plus a continuous Picatinny rail, providing plenty of space for all your favorite accessories.
