FAB Defense | Vanguard AR M-LOK Handguard System

The FAB Defense Vanguard AR is a slim M-LOK handguard designed for carbine-length AR-15/M4 platforms that do not use a gas block. It integrates an innovative heatshield for thermal insulation and accepts M-LOK accessories directly or via M-LOK 1913 Picatinny rail sections. The unit includes two integrated QD sling swivel sockets and multiple M-LOK attachment positions to support modular accessory layouts. Installation is intended to be straightforward and does not require a gunsmith.
