CT Gen Stat § 53-206i (2020)
2020 Connecticut General Statutes|Title 53 - Crimes|Chapter 943 - Offenses Against Public Peace and Safety|Section 53-206i - Manufacture of firearm from polymer plastic without detectable security exemplar. Prohibited. Penalty.

 (a) No person shall manufacture any firearm from polymer plastic that, after removal of grips, stocks and magazines, is not as detectible as the security exemplar, by walk-through metal detectors calibrated and operated to detect the security exemplar.(b) If the court finds that a violation of this section is not of a serious nature and that the person charged with such violation (1) will probably not offend in the future, (2) has not previously been convicted of a violation of this section, and (3) has not previously had a prosecution under this section suspended pursuant to this subsection, the court may order suspension of prosecution. The court shall not order suspension of prosecution unless the accused person has acknowledged that he or she understands the consequences of the suspension of prosecution. Any person for whom prosecution is suspended shall agree to the tolling of any statute of limitations with respect to such violation and to a waiver of his or her right to a speedy trial. Such person shall appear in court and shall be released to the custody of the Court Support Services Division for such period, not exceeding two years, and under such conditions as the court shall order. If the person refuses to accept, or, having accepted, violates such conditions, the court shall terminate the suspension of prosecution and the case shall be brought to trial. If such person satisfactorily completes such person's period of probation, he or she may apply for dismissal of the charges against such person and the court, on finding such satisfactory completion, shall dismiss such charges. If the person does not apply for dismissal of the charges against such person after satisfactorily completing such person's period of probation, the court, upon receipt of a report submitted by the Court Support Services Division that the person satisfactorily completed such person's period of probation, may on its own motion make a finding of such satisfactory completion and dismiss such charges. Upon dismissal, all records of such charges shall be erased pursuant to section 54-142a. An order of the court denying a motion to dismiss the charges against a person who has completed such person's period of probation or terminating the participation of a defendant in such program shall be a final judgment for purposes of appeal.(c) Any person who violates any provision of this section shall be guilty of a class C felony for which two years of the sentence imposed may not be suspended or reduced by the court, and five thousand dollars of the fine imposed may not be remitted or reduced by the court unless the court states on the record its reasons for remitting or reducing such fine, and any firearm found in the possession of any person in violation of any provision of this section shall be forfeited.(d) For purposes of this section, “firearm” means firearm, as defined in section 53a-3, but does not include the frame or receiver of any such weapon and “security exemplar” means “security exemplar” as defined in 18 USC 922(p), as amended from time to time, and any regulation adopted thereunder.(P.A. 19-6, S. 4.)
