Mass. Gen. Laws ch. 214 § 7B
Notwithstanding the provisions of any general or special law, rule or regulation to the contrary, no owner of a rifle, pistol, silhouette, skeet, trap, blackpowder, or other similar range shall be liable in any civil action or criminal prosecution in any matter relating to noise or noise pollution resulting from use of the range, provided said owner of the range was in compliance with any applicable noise control law, ordinance or by-laws in existence at the time of the construction of such range.
No owner shall be liable in any action for nuisance, and no court shall enjoin the use or operation of said range on the basis of noise or noise pollution, provided said owner was in compliance with any noise control law, ordinance or by-laws in existence at the time of the construction of the range.
The exemptions from liability and the immunities from prosecution provided in this section shall also extend to any owner who, in order to satisfy a requirement of law, regulation or by-law, relocates his range within the same parcel of land or a contiguous parcel of land, owned by him at the time that the commonwealth or its political subdivision commences enforcement of such a requirement or that the owner voluntarily complies with such a requirement. In order to maintain these exemptions from liability and immunities from prosecution, owners who relocate their ranges pursuant to the preceding sentence shall remain in compliance with the applicable noise control laws, ordinances or by-laws in existence at the time of the construction of the original range described in the first paragraph.
No standards in rules adopted by any state, city, or town agency for limiting levels of noise in terms of decibel level which may occur in the outdoor atmosphere shall apply to the ranges exempted from liability under the provisions of this section. Such ranges shall be prohibited from operating between the hours of ten o'clock post meridian and eight o'clock ante meridian unless otherwise allowed by the local governing body.
