I’m not sure Joe Biden would approve. Didn’t he specify using a double-barrel shotgun?
It doesn’t matter, by the 6 o’clock news this will be an AKR-47/15, fully tracked, tractor-drawn, belt-fed, highly concealable cheap Saturday Night Special carbonizer (with mutate capacity) that can be bought without any ID at any gun show, NRA-approved.
Just like the Washington Naval Yard shooter used an AR-15 pump action shotgun.
