This bill, titled the "Restoring the Armed Career Criminal Act," significantly modifies sentencing provisions for individuals convicted of unlawful firearm possession. It amends title 18, United States Code, specifically targeting those who violate section 922(g) by possessing a firearm after having accumulated three or more prior serious felony convictions . The legislation aims to enhance penalties for armed career criminals by establishing more stringent sentencing guidelines. Under the revised law, individuals meeting these criteria will face a mandatory minimum sentence of 15 years and a maximum of 30 years imprisonment, with no possibility of a suspended sentence or probation. The bill also redefines "serious felony conviction" to include any felony offense with a statutory maximum term of not less than 10 years, or a group of convictions resulting in a total imposed term of at least 10 years. These amendments apply to offenses committed after the bill's enactment and explicitly state that they do not create a right to challenge imposed sentences.
