An apparent mugshot of Fields was posted to the Magpul Industries Facebook page by a private user after legislation to limit gun magazine capacity, which was cosponsored by Fields, drove the company to announce that it was closing its doors in Colorado and moving out of state.

Rep. Fields has sponsored multiple gun control bills currently under debate in the Colorado Legislature, including legislation to ban on magazines with the capacity to hold more that 15 rounds, criminalize the private sale or transfer of a firearm without a background check,ban on concealed carry permits on the college campuses, and increase background check fees.

Fields has also co-sponsored Sen. Evie Hudak's legislation which would not only strip anyone subject to a restraining order of their Second Amendment rights, but would also require the same to relinquish any firearms they own to the state.

Sen. Hudak has recently been in the national spotlight for remarks she made to rape survivor Amanda Collins. During testimony from Collins which detailed how her attacker was able to target her while she was unarmed due to a campus ban on concealed carry in Nevada, Hudak told Collins that "actually statistics are not on your side even if you had a gun."
