Far be it for a former blue-suiter such as myself to contradict the 8 years of experience by Marine Acree, but I don't think that the Marine Corps gave Marine Acree much training on the Slide Fire Solutions bump fire stock, operation of which relies on forward pressure applied to the foregrip and the free ability of the weapon to recoil into the shoulder.
Not something that can be done with any reliability from a bipod or tripod.
I also don't think that Marine Acree has any experience with 22,000 targets herded into an acre and a half of space, and how many hits one could make without any magnified optics at all.
Paddock had red dot sights on his bump fire stock equipped rifles, and a red dot is plenty accurate enough to lob rounds into the concert area.
Precision accuracy???? What a crock....
More drivel for the mush minds.
Thank you for knowing how to bump fire. Ha. So sick of hearing nonsense.
