[citation needed] The EX-34 was specifically designed for use as a coaxial weapon in armoured vehicles, and has a number of features that make it suitable for this role.

The gun is externally powered, meaning that misfires do not need to be manually cleared; instead, the rounds are simply ejected.

Additionally, all gas generated by firing is vented through the barrel and ejection tube, preventing the build-up of toxic gases inside the armoured vehicle.

Problems with the electrical systems in the Warrior IFV have caused the weapon to fire without warning several times, resulting in the army issuing a safety notice.

[4] Additionally, the Challenger 2 mounting of the weapon cannot be accurately aimed using the main sight below a minimum range of 200 meters, which has led to at least one death from "friendly fire".
