List of Gundam/mobile suit's weapons:
One beam saber is stored in each of the AGE-FX's arm shields. But unlike the ones used by the Gundam AGE-3 Normal, AGE-FX's beam sabers can only be deployed directly from the forearm shields for rapid draw-and-strike purposes.
A remote weapon armed with a single DODS Cannon and Beam Torches (beam saber), a total of six A-Funnels are mounted on both shins, arms, and waist of the Gundam AGE-FX. It is fitted with various types of sensors and a high-precision camera . The A-Funnel is an autonomous weapon as its operation does not rely on the abilities of an X-Rounder. It is equipped with a dedicated operating system and functions more like an unmanned MS rather than a Bit. The A-Funnels function as gun turrets when combined with the AGE-FX or hand-held as large beam sabers by releasing the Beam Torch limiters.
The main Armament of Gundam AGE-FX. Its capabilities are far superior to the SigMaxiss Rifle in terms of attack power and firing range, while having its size drastically reduced. The rifle has two main modes: Normal Mode, which is used as a regular rifle, and Charge Mode, where the side barrel parts are expanded for a more powerful blast. This is somewhat similar to the dual-mode function used in Gundam AGE-1 Normal's DODS Rifle. However, like the Gundam AGE-1 Normal's DODS Rifle, the Stungle Rifle has a limited amount of shots, enough to keep a running battle going for some time, but eventually repeated use without resupply will rendering the weapon useless.
The Charge Mode is activated by opening its side barrels and the AGE-FX fires the Charged Blast by holding its foregrip with the left hand, similar to the DODS Rifle used by Gundam AGE-1 Normal, and fires a powerful blue-colored beam cannon blast. Kio used this mode to destroy the connectors of La Gramis that has docked with Second Moon in order to separate the ship from the colony in an attempt to save Second Moon from collapsing and destroy all the Vagan people living there as a result.
This mode of the Stungle Rifle adds a large bazooka attachment, allowing AGE-FX to automatically fire the same blue-colored shot as the Stungle Rifle Charge Mode without the requirement to charge first as well as using the foregrip when firing, and can be used for longer periods of time without the need for resupplying the weapon itself. Kio used this in the final Battle against Vagan Gear Sid, although the weapon was only used once before being blown up by the latter.
