Vermont's new gun laws prompted someone listed as living in Derby Line to post a used bump stock on eBay this week.

With less than two weeks until the gun accessories become illegal in Vermont, the seller was eager to sell at an asking price of $75, which had been bid up to $102.50 (plus $7.25 shipping) by Wednesday afternoon.

"Used three times works great!!" the seller wrote in the listing for the bump stock, a device that increases the rate of fire of a semiautomatic weapon. "Have to get rid of it vermont put a ban on them I will not ship to a state that has a ban on them!!"

Oct. 1 brings full implementation of the restrictions on gun equipment that Gov. Phil Scott signed in April.

The law makes the possession of a bump stock a misdemeanor, and forbids the general public from buying or transferring gun magazines that hold more than 15 round for a handgun, and 10 rounds for a rifle (Gun dealers were given until Oct. 1 to sell any magazines they had in stock).

Gun-rights groups are fighting the restrictions in court, arguing both laws infringe on Vermonters' right to bear arms. As neither bump stocks nor magazines are registered, the laws rely in large part on Vermonters' voluntary compliance.

Rep. Martin LaLonde, who helped write the laws, does not expect Vermont police to go out searching for bump stocks or illegal magazines.

"Throughout this whole process, gun-rights representatives repeatedly said that Vermonters are law abiding citizens, and I agree," said LaLonde, D-South Burlington. "And I expect that they will abide by the law."

Overall, LaLonde noted that Vermont retailers would no longer carry the banned equipment, and online retailers such as Cabela's would restrict shipping of certain items to Vermont.

"If there's an individual who has ill intent and wants to stock up, let's make it a little more difficult for the individual to obtain something that makes the weapon more lethal," LaLonde said.

Bump stocks lose ground across U.S.

No one knows how many bump stocks exist in Vermont. There may be at least 280,000 bump stocks nationwide, the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives estimated this year when it proposed a rule that would effectively ban bump stocks on the federal level by including them in the definition of a machine gun. President Donald Trump has indicated support for the national ban.

"They're a gimmick or a toy," said Sen. John Rodgers, D-Essex/Orleans, when the Senate was debating the bump stock ban earlier this year. Rodgers said he was concerned that people would be forced to relinquish property without compensation.

The devices are unwelcome in a growing number of states following the mass shooting at a Las Vegas music festival in October 2017, where the gunman used bump stocks.

Massachusetts, New Jersey, Rhode Island, Hawaii, Washington, Delaware and California have outlawed bump stocks, news reports show. Florida is poised to join the list in October, and Maryland will follow a year later.

Police disposal programs have not been used

Vermont State Police announced Monday that they will accept bump stocks from any person who wants to anonymously relinquish the device in advance of the Oct. 1 ban. People can bring their bump stocks, disconnected from a weapon, to any state police barracks during normal business hours. The devices will be destroyed.

Vermont State Police Capt. Timothy Clouatre said he was not aware of any bump stocks collected at any state police barracks as of Wednesday.

Similar voluntary collection efforts around the country have taken in a meager number of bump stocks:

In Massachusetts, state police collected just three bump stocks and one trigger crank when the state's bump stock ban took effect on Feb. 1, CBS Boston reported.

New Jersey residents had about three months to turn over their bump stocks to state police. As of May, the New Jersey State Police had not received any bump stocks, according to Stateline, a state policy reporting initiative of Pew Charitable Trusts.

In Denver, local media outlets reported that no one had turned over a bump stock to Denver police following a municipal ban in late January.

Other states have passed buyback programs to compensate for the value of an illegal bump stock. Washington plans to offer $150 per bump stock, and Delaware designed a $100 buyback program.

The ATF noted that since many bump stocks are made of plastic, people could easily destroy them with a hammer to comply with a federal ban.

Lawsuits continue in state court

Two lawsuits are challenging the constitutionality of Vermont's new gun laws.

The first lawsuit, filed by the Vermont Federation of Sportsmen's Clubs and others at Vermont Superior Court in Montpelier, challenges the magazine limit, saying "it will make law-abiding Vermont citizens more vulnerable to criminal attack by depriving them of commonly-owned ammunition magazines."

The second lawsuit, filed last month by Gun Owners of Vermont at Vermont Superior Court in Newfane, challenges the constitutionality of several other restrictions, including the bump stock ban, the requirement that private gun transfers must go through the background check system, and the requirement that people under age 21 must take a hunter safety course before purchasing a gun.

Plaintiffs in both lawsuits argue the new laws violate protections in the Vermont Constitution.
