SCDTV has some photos of the Asura Dynamics Gen 1 Carbon Fiber Handguard for M4 AEG/GBB. The handguard doesn't have a rail system but has a smooth surface that can avoid snags on your clothing or on twigs and branches. For those who want a minimalist but still a good looking M4 AEG or GBB, this can the handguard of choice.
