Chapter 269 - Crimes Against Public Peace
Section 11c - Removal or Mutilation of Serial or Identification Numbers of Firearms; Receiving Such Firearm; Destruction

Section 11C. Whoever, by himself or another, removes, defaces, alters, obliterates or mutilates in any manner the serial number or identification number of a firearm, or in any way participates therein, and whoever receives a firearm with knowledge that its serial number or identification number has been removed, defaced, altered, obliterated or mutilated in any manner, shall be punished by a fine of not more than two hundred dollars or by imprisonment for not less than one month nor more than two and one half years. Possession or control of a firearm the serial number or identification number of which has been removed, defaced, altered, obliterated or mutilated in any manner shall be prima facie evidence that the person having such possession or control is guilty of a violation of this section; but such prima facie evidence may be rebutted by evidence that such person had no knowledge whatever that such number had been removed, defaced, altered, obliterated or mutilated, or by evidence that he had no guilty knowledge thereof. Upon a conviction of a violation of this section said firearm or other article shall be forwarded, by the authority of the written order of the court, to the colonel of the state police, who shall cause said firearm or other article to be destroyed.
