"...a vast amount of guns..."
Such as what? Half a dozen? How many were assault pistols?
Not even a half dozen. Two handgun frames, one AR lower, size handgun slides, NO barrels, and what looks like a mold for casting AR-15 resin lowers.
That's not a "vast amount." All that doesn't add up to a single, functional firearm.
[Edit] I take it back. The handgun with the slide attached appears to have a barrel. So maybe one functional firearm.
