Max Factory Zoanoid Buster & Chronos laser rifles

Who can forget Murakami's kickass anti-zoanoid pistol? containing three dum dum rounds that can penetrate the flesh of normal zoanoids with ease, and even deter lower level Hyper Zoanoids. Its supposedly a Max Factory custom, which begs the question...Who is Max Factory and do they still exist as a weapons manufacturer even after the events of X-Day? Are they an underground weapon manufacturing group? I can't help but be curious about the people who made his weapon and if they knew what Murakami was involved in or were in the dark, just another custom job, no questions asked as long as payment was made. In real life Max Factory is a toy and figurine making company, though I gotta wonder about their identity in the Guyververse. Max Pharmaceuticals was the cover for the Japan Branch of Chronos, so maybe there's a connection between the two?

Also, could Murakami's old trademark weapon be modified for use by human hands? The recoil from his gun was so powerful he had to transform his hand and arm to be able to use it, and the weight of it alone made it difficult for a normal human like Tetsuro to lift it....I suspect a normal person's wrist would have been shattered if they tried to fire it.

There's also the matter of those laser rifles Chronos troopers have been seen carrying, I can't recall if we've ever seen those weapons in action at all. We can assume they're more advanced & have more penetrating power than conventional firearms, enough to kill maybe a low level zoanoid, though I guess their primary purpose was to provide Chronos agents with a means by which to defend themselves or kill a target without having to transform & give away their cover prior to the events of X-Day.
