Revanchist Airsoft got this quick promo video of the Revanchist Airsoft Lightweight Carbon Fiber Handguard V2 which seems to be snapped up quickly as it is out of stock at arsoft shops in Hong Kong. The Revanchist Airsoft Lightweight Carbon Fiber M-lok Handguard Rail is a durable and lightweight handguard for the Tokyo Marui MWS series gas blowback rifles. It features M-Lok slots and a Picatinny top rail for mounting accessories.

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.
