Sixteenth, That no licensee shall sell, lease, rent, transfer or deliver or offer for sale, lease, rent, transfer or delivery to any person any assault weapon or large capacity feeding device that was not otherwise lawfully possessed on September 13, 1994. Seventeenth, That any licensee from whom a rifle, shotgun, firearm or machine gun is lost or stolen shall report such loss or theft to the licensing authority and the executive director of the criminal history systems board forthwith. Such report shall include a complete description of the weapon, including the make, model, serial number and caliber and whether such weapon is a large capacity weapon. Eighteenth, That no licensee shall sell, rent, lease, transfer or deliver or offer for sale, lease, transfer or delivery any firearm, to any purchaser in the commonwealth unless such sale is to a business entity that is primarily a firearm wholesaler and the sale, by its terms, prohibits the purchaser from reselling such firearm to a firearm retailer or consumer in the commonwealth if such firearm has a frame, barrel, cylinder, slide or breechblock that is composed of: (i) any metal having a melting point of less than 900 degrees Fahrenheit; (ii) any metal having an ultimate tensile strength of less than 55,000 pounds per square inch; or (iii) any powdered metal having a density of less than 7.5 grams per cubic centimeter. This clause shall not apply to any make and model of firearm for which a sample of three firearms in new condition all pass the following test: Each of the three samples shall fire 600 rounds, stopping every 100 rounds to tighten any loose screws and to clean the gun if required by the cleaning schedule in the user manual, and as needed to refill the empty magazine or cylinder to capacity before continuing. For any firearm that is loaded in a manner other than via a detachable magazine, the tester shall also pause every 50 rounds for ten minutes. The ammunition used shall be the type recommended by the firearm manufacturer in its user manual or, if none is recommended, any standard ammunition of the correct caliber in new condition. A firearm shall pass this test if it fires the first 20 rounds without a malfunction, fires the full 600 rounds with not more than six malfunctions and completes the test without any crack or breakage of an operating part of the firearm. The term "crack'' or "breakage'' shall not include a crack or breakage that does not increase the danger of injury to the user. For purposes of evaluating the results of this test, malfunction shall mean any failure to feed, chamber, fire, extract or eject a round or any failure to accept or eject a magazine or any other failure which prevents the firearm, without manual intervention beyond that needed for routine firing and periodic reloading, from firing the chambered round or moving a new round into position so that the firearm is capable of firing the new round properly. "Malfunction'' shall not include a misfire caused by a faulty cartridge the primer of which fails to detonate when properly struck by the firearm's firing mechanism. Nineteenth, That no licensee shall sell, rent, lease, transfer or deliver or offer for sale, lease, transfer or delivery any firearm to any purchaser in the commonwealth unless such sale is to a business entity that is primarily a firearms wholesaler, and the sale, by its terms, prohibits such purchaser from reselling such firearm to a firearm retailer or consumer in the commonwealth if such firearm is prone to accidental discharge which, for purposes of this clause, shall mean any make and model of firearm for which a sample of five firearms in new condition all undergo, and none discharge during, the following test: Each of the five sample firearms shall be: (a) test loaded; (b) set so that the firearm is in a condition such that pulling the trigger and taking any action that must simultaneously accompany the pulling of the trigger as part of the firing procedure would fire the handgun; and (c) dropped onto a solid slab of concrete from a height of one meter from each of the following positions: (i) normal firing position; (ii) upside down; (iii) on grip; (iv) on the muzzle; (v) on either side; and (vi) on the exposed hammer or striker or, if there is no exposed hammer or striker, the rearmost part of the firearm. If the firearm is designed so that its hammer or striker may be set in other positions, each sample firearm shall be tested as above with the hammer or striker in each such position but otherwise in such condition that pulling the trigger, and taking any action that must simultaneously accompany the pulling of the trigger as part of the firing procedure, would fire the firearm. Alternatively, the tester may use additional sample firearms of the same make and model, in a similar condition, for the test of each of these hammer striker settings. Twentieth, That no licensee shall sell, rent, lease, transfer or deliver or offer for sale, lease, transfer or delivery, any firearm to any purchaser in the commonwealth unless such sale is to a business entity that is primarily a firearm wholesaler, and the sale, by its terms, prohibits the purchaser from reselling such firearm to a firearm retailer or consumer in the commonwealth if such firearm is prone to: (i) firing more than once per pull of the trigger; or (ii) explosion during firing. Twenty-first, That no licensee shall sell, rent, lease, transfer or deliver or offer for sale, lease, transfer or delivery any firearm to any purchaser in the commonwealth unless such sale is to a business entity that is primarily a firearm wholesaler and the sale, by its terms, prohibits the purchaser from reselling such firearm to a firearm retailer or consumer in the commonwealth if such firearm has a barrel less than three inches in length, unless the licensee discloses in writing, prior to the transaction, to the prospective buyer, lessee, deliveree or transferee the limitations of the accuracy of the particular make and model of the subject firearm, by disclosing the make and model's average group diameter test result at seven yards, average group diameter test result at 14 yards and average group diameter test result at 21 yards. For purposes of this clause, "average group diameter test result'' shall mean the arithmetic mean of three separate trials, each performed as follows on a different sample firearm in new condition of the make and model at issue. Each firearm shall fire five rounds at a target from a set distance and the largest spread in inches between the centers of any of the holes made in a test target shall be measured and recorded. This procedure shall be repeated two more times on the firearm. The arithmetic mean of each of the three recorded results shall be deemed the result of the trial for that particular sample firearm. The ammunition used shall be the type recommended by the firearm manufacturer in its user manual or, if none is recommended, any standard ammunition of the correct caliber in new condition. No licensee shall sell any rifle or shotgun, contrary to the provisions of section one hundred and thirty or section 131E.Clauses Eighteenth to Twenty-first, inclusive, of the first paragraph shall not apply to: (i) a firearm lawfully owned or possessed under a license issued under this chapter on or before October 21, 1998; (ii) a firearm designated by the secretary of public safety, with the advice of the gun control advisory board, established pursuant to section 1311/2 of chapter 140, as a firearm solely designed and sold for formal target shooting competition; (iii) a stun gun, as defined in section 121; or (iv) a firearm designated by the secretary of public safety, with the advice of the gun control advisory board, established pursuant to section 1311/2 of chapter 140, as a firearm or pistol solely designed and sold for Olympic shooting competition.

No person licensed under the provisions of section 122 or section 122B shall fill an order for such weapon, ammunition or ammunition feeding device that was received by mail, facsimile, telephone or other telecommunication unless such transaction or transfer includes the in-person presentation of the required card, proof, license or permit as required herein prior to any sale, delivery or any form of transfer of possession of the subject weapon, ammunition or ammunition feeding device. Transactions between persons licensed under section 122 or between federally licensed dealers shall be exempt from the provisions of this paragraph.The licensing authority shall enter, one time per calendar year, during regular business hours, the commercial premises owned or leased by any licensee, wherein such records required to be maintained under this section are stored or maintained, and inspect, in a reasonable manner, such records and inventory for the purpose of enforcing the provisions of this section.
