According to the Washington Examiner:
The bill — sponsored by Sen. Dianne Feinstein, D-Calif., and other Senate Democrats — would make it illegal to sell more than 200 types of semi-automatic weapons as well as magazines holding more than ten rounds of ammunition. The proposal would also ban devices that ramp up firing speed, such as the bump stock used in the Las Vegas shooting last month.
The bill is similar to a 2013 measure Feinstein introduced following the mass shooting at Sandy Hook Elementary School and comes after a string new deadly shootings in October and November.
It would expand background checks to all gun sales and require “a safe storage requirement for grandfathered firearms.”
