Magpul, one of the country's largest producers of ammunition magazines for guns, is leaving Colorado and moving operations to Wyoming because of Colorado laws that include restrictions on how many cartridges a magazine can hold. The Wyoming State Loan and Investment Board is considering a $13 million incentive package to help Magpul make the move. (AP Photo/Brennan Linsley, File)
