Unfooooortunately, nullius' skills are too limited to make a proper legal assessment of the case, even though he seems to have a lot of free time. His activity as a hobby lawyer has failed. Perhaps he should study the
Assault weapons legislation in the United States at first. Furthermore, he might study the Arkansas Code before talking more bullshit. I will now make the relevant citations for him:
AR Code § 5-73-202(2) (2019)
“Machine gun” means a weapon of any description by whatever name known, loaded or unloaded, from which more than five (5) shots or bullets may be rapidly, or automatically, or semi-automatically, discharged from a magazine, by a single function of the firing device
AR Code § 5-73-205(a4) (2017)
Possession or use of a machine gun is presumed to be for an offensive or aggressive purpose: When empty or loaded pistol shells of 30 (.30 in. or 7.63 mm.) or larger caliber which have been or are susceptible of use in the machine gun are found in the immediate vicinity of the machine gun.
AR Code § 5-73-204 (2017)
Possession or use of a machine gun for offensive or aggressive purpose is declared to be a crime punishable by imprisonment in the state penitentiary for a term of not less than ten (10) years. Now we come to the nice weapon deals BayAreaCoins is offering here. As one can see all the guns are kept loaded (which is not good for the magazine springs, by the way):


Now you can come back again waving the phrase "FFL to FFL", but the Bureau of Alcohol, Tobacco, Firearms and Explosives, the FBI, and the Arkansas State Police don't give a damn about your limited abilities as a hobby lawyer! Onlookers here can only conclude that the dealer offering these military weapons on a crypto forum must have mental health problems, as must all his supporters here. Evaluated together with the documented continuous cyber harassment by the dealer, this was a clear case that had to be reported to the above mentioned authorities.
