The LANTAC SPADA-ML 6.75" M-LOK Handguard is machined from extruded 6005A-T6 aluminum and finished with Type 3 hardcoat anodizing in a Class 2 deep black. This construction provides a durable and robust design with an ultra-narrow diameter. The handguard features a patented anti-slip and anti-rotation system that strengthens the connection in the receiver end area and allows for strong clamping onto the barrel nut. The handguard cannot be removed from the barrel nut without removing all three fixing screws.
