The Leadwall has a magazine of 12 shots but each pull of the trigger consumes 3 shots, which means it can only fire 4 times before it requires a reload. This low magazine capacity is complemented with a fairly high reload time. The weapon deals high damage at short range, firing 3 spread projectiles that bounce off of walls, shredding Titan armor and eliminating pilots in one shot. However, the shots will dissipate after a certain distance, making it useless for long range combat.
The Leadwall shares many similarities to the Triple Threat from the original Titanfall, using a similar magazine drum, but having 3 barrels instead of 1. Even the concept art depicts the weapon with the name Triple Threat.
