I can agree, to a point.I'm not surprised at the response you got @ratski. There are lots of folks that I wouldn't want to see even attempt to shoot full auto, especially so in an enclosed range building.
I've been shooting full auto form more than 20 years.
I'm not a "mag dump" kind of shooter, but invariably some folks want to do that.
Even my staff shoot FA well.
We have been down that road before
And when you consider the cost of acquisition of these things, I'd be willing to bet that 99.9% of full auto shooters are not novice shooters.
Some can be.
And ranges that rent Class III to people with no experience will see issues, but that isn't the case here.
