Meh, slide-fire stock, no problem. Run a few mags with a stock like that and it’s no problem, even if there’s more muzzle climb.
You break down an AR-15 one or two times and it’s a snap. 10 or more times..? You can do it with your eyes closed.
Training..? Even a fool can do it, though if you’re fussy there are 100 YouTube vids that can put you straight, in way less time than in the miitary, too.
If you didn’t want to go the slide-fire stock route you can also use the AutoGlove, though the BATF recently ruled it’s not legal.
The range was a bit far but this guy was basically spraying a crowd of 22,000 people below him. Many of them actually LAID DOWN for him for some minutes, giving him fantastic stationary targets.
Later crowds of them took refuge in —get this— a TENT.
I’d say a total idiot could manage the technical aspects of his grisly work.
How did he get the weapons up there..? He broke them down, placed them in bags and then CARRIED them up there. Easy.
Crates of ammo..? They could be pre-loaded into mags, then put into common bags, but there are also big, roller-wheel Samsonites that will accomodate entire CRATES of ammo, no prob.
The technicals are actually pretty easy.
Spot.On.
God bless you. Seriously. Ive read way too much ignorant junk about guns and wacked out theories about the events before and during the past several days... Your post lays it out simply, and reasonably. I couldnt have said it better.
