The FSD (Prototype Long-Range Beam Rifle Equipped) will be released exclusively at Gundam Base.
After reading the comics, I really wanted to give it a long-range beam rifle, so I attempted to create a "homemade" long-range beam rifle equipped version, rather than a "prototype."
Since I couldn't make it from scratch, I searched everywhere for something similar and created something that "looks like a prototype long-range beam rifle" based on a weapon for the 30MM Alto.
I hope I can buy the Gundam Base limited edition one day.
