Democratic lawmakers say they're getting serious about enforcing Colorado's ban on high-capacity ammunition magazines. But their solution would take a wide range of firearms off the shelves of gun stores statewide, including some of the most popular varieties of semi-automatics.

Past efforts to ban so-called assault rifles have failed, but this year's bill debuted with an unprecedented level of support. Still, it's future is far from certain.

CPR's Bente Birkeland, KUNC's Lucas Brady Woods and The Colorado Sun's Jesse Paul explain what the bill would do, and why -- if it ultimately becomes law -- it would be one of the most sweeping gun restrictions in the nation.
