'Primary this wimp': Gun nuts seethe at military vet GOP lawmaker after he comes out for banning AR-15
Rep. Brian Mast (R-FL)

Rep. Brian Mast (R-FL) on Friday published an editorial in the New York Times calling for a ban of AR-15-style rifles, which he says are not weapons that should be used by civilians.

Speaking of his experience in the military, Mast wrote that he once regularly used an AR-15-style rifle while serving his country -- and he said last week's massacre at the Marjory Stoneman Douglas High School in Parkland, Florida showed him that these kinds of weapons should only be used by the military, and not by citizens in their everyday lives.

"We used it because it was the most lethal -- the best for killing our enemies," he explained. "And I know that my community, our schools and public gathering places are not made safer by any person having access to the best killing tool the Army could put in my hands. I cannot support the primary weapon I used to defend our people being used to kill children I swore to defend."

While Mast's stance on banning such weapons earned him praise on social media from some gun control advocates, many gun enthusiasts took to Twitter to let him know that his political career was about to be over thanks to his new stance on the AR-15.
