I heard on FOX that one type of the shells found were .223. Makes me think AR, illegally modified with an illegal drum. .223’s have a very flat trajectory, and from that hotel room he was just spraying lead in the general direction of the concert. Target rich environment indeed.
There are dozens of legal drums on the market; why do you think he had an "illegal" one?
Or, is that just typical gun ignorance talking...?
Drums aren’t illegal. Any competent machinist can modify. hussein sotero had 8 yrs to seed his minions throughout the military. Lots of stuff goes missing. They came from the local cartel connection. I’m sure there is regular route to LV from Mexico.
