To be fair, there isn’t a whole ton of legitimate reasons why civilians need .50 cal rifles. I wonder if republicans will oppose the bill because anything that infringes on the rights of guns is abhorrent to them. Or if they’ll champion it, because Mexican Cartel’s use .50 cal rifles.
I’m willing to bet it’ll be the first option, because just like the border bill, they don’t want anything that’ll take away the drum they like to beat to rile up their base. If they only like complaining about a problem to scare people, and actively avoid fixing that problem.
