thats the whole point, this guy was not a "gun enthusiast" a gun enthusiast does not buy a dozen and a half AR15's where packs of 3s and 4s are in the same configuration nor do they typically buy overpriced retarded **** like a daniels defense rifle that is what suburban yuppie does. if a shooter wants something high end they usually build it themselves just like a "computer person" picks each part and builds it, he does not go to wal mart and grab a dell off the shelf, that is what a retard that does not know anything about computers would do. if a shooter has a dozen ar15s they are going to be in assorted configurations and calibers, i know several people with a half dozen or more AR type rifles, none of them have two exactly identical guns. you can profile people based off of the firearms they use, this guy was a ***** liberal all day long as that is the type of ******* that goes to mass murder a bunch of people with a "bumpstock" at the near max lethal range of his primary weapon while carrying more weight in the guns (20+) he wants to get banned than the ammunition he intends to shoot, there are many things like that. another example is the two foot long 100 round surefire stick mag i saw in another photo hanging out of one of the guns, a gun guy would have used a drum especially one with millions of dollars to throw around.
i have heard the "barrel overheating" nonsense numerous times which like most of the ***** in the headlines is spouted by people who have never shot a gun, the guy apparently did not have enough ammunition to cause even two of the weapons to fail and the gas tube always blows (around 300 - 500 rounds of sustained fire with no cool off) long before the barrel does anyway on an overheated ar15, a "gun person" would know that, they would also not set up 350 yards away from the closest line of people they want to shoot with a .223
to most people this will just look like another postal worker type, however if you know the "tastes" americans tend to have in their firearms and are familiar with the last 15+ years of the lefts legislative attempts to eliminate private gun ownership it is night and day evident that this was a politically motivated leftwing *****.
and yes, this was on the strip. on the OUTSKIRTS of the strip at the very end of it. like i said in my first response. not sure why this is even being debated. when you drive through vegas the ***** airport is the end of the strip and that whole surrounding area rapidly descends from "vegas" and its bright lights into "get robbed town" and its methheads instead. he certainly had ample opportunities to shoot at a larger crowd but he didn't he went to the white conservative trump voter gathering which was the point.
