Connecticut law imposes additional sentence enhancements when a firearm is used during the commission of certain crimes. Under CGS 53-202k, a defendant convicted of a Class A, B, or C felony who used, was armed with and threatened the use of, displayed, or represented possession of a firearm during the offense faces an additional 5-year nonsuspendable mandatory sentence, served consecutively to the underlying felony sentence. Under CGS 53-202j, if the crime was committed with an assault weapon, the additional nonsuspendable mandatory sentence increases to 8 years.[13]
