BOULDER — Despite unanimously passing Boulder City Council, a ban to assault weapons won't go into effect Tuesday night.

Council voted unanimously to ban the sale and possession of assault weapons, bump stocks and high-capacity magazines.

Several amendments were discussed, including raising the age to buy firearms to 21 instead of 18 - and those amendments will have to be discussed at the third meeting on this matter, according to the city's Twitter account.

The council set aside two hours to discuss the issue - the second meeting on it. Council decided to amend the ban, so they'll need the third meeting before it's finalized.

Gun control advocates in Boulder had urged the city council to pass the city's proposed ban on assault weapons, bump stocks and high-capacity magazines as soon as possible.

Councilwoman Lisa Morzel predicted the likelihood of council members offering revisions to the draft could push the ban to a third reading before it gets adopted. It's not immediately clear when that could be.

Those exempted from the ban would include law enforcement officials, military service members and holders of Federal Firearm Licenses, among others, per the city's Twitter account.
