bump stock

Bump stocks or bump fire stocks are gun stocks that can be used to assist in bump firing. Bump firing is the act of using the recoil of a semi-automatic firearm to fire ammunition cartridges in rapid succession.

The legality of bump stocks in the United States came under question following the 2017 Las Vegas shooting, in which 60 people were killed and 867 people injured. The gunman was found to have fitted them to his weapons. Several states passed legislation restricting ownership of bump stocks following this shooting and the one at Marjory Stoneman Douglas High School 4 months later. The U.S. Justice Department banned them at the federal level in December 2018.

Bump fire stocks

Bump fire stocks are gun stocks that are specially designed to make bump firing easier, but do not make the firearm automatic. Essentially, bump stocks assist rapid fire by "bumping" the trigger against one's finger (as opposed to one's finger pulling on the trigger), thus allowing the firearm's recoil, plus constant forward pressure by the non-shooting arm, to actuate the trigger. Bump fire stocks can be placed on a few common weapon platforms such as the AR or AK families. They can achieve rates of fire between 400 and 800 rounds per minute depending on the gun. By 2018, bump fire stocks in the United States were sold for around $100 and up, with prices increasing prior to enactment of federal regulation.

Slide Fire Solutions, the inventor, patent holder, and leading manufacturer of bump stocks, suspended sales after bump stocks were used in the 2017 Las Vegas shooting, and resumed sales a month later. On May 20, 2018, 95 days after the Stoneman Douglas High School shooting, Slide Fire Solutions permanently halted sales and production of its products.

History of regulation

In 2002, one of the first bump stock-type devices, the ''Akins Accelerator'' invented by Bill Akins, was deemed by the US Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to not be a "machinegun". The Akins Accelerator used an internal spring to force the firearm forward to re-make contact with the trigger finger after the recoil of the previous shot pushed the firearm rearward. The ATF interpreted a "single function of the trigger" to mean a "single movement of the trigger", and since the trigger moved for each shot, the Akins Accelerator was deemed to not be a machinegun. Later, in 2006, the ATF reversed course and reinterpreted the language to mean "single pull of the trigger", which reclassified the Akins Accelerator as a machinegun. The Eleventh Circuit Court of Appeals upheld the new interpretation in February 2009.

More modern bump stocks were invented by Slide Fire Solutions founder Jeremiah Cottle as a replacement stock for people who have limited hand mobility. Such bump stocks have no internal spring and require constant forward pressure by the non-shooting arm in order to maintain continuous fire. Between 2008 and 2017, the ATF issued ten letter rulings that classified bump stocks as a "firearm part", which are unregulated. However, in March 2018, as a result of the use of bump stocks in the 2017 Las Vegas shooting, the U.S. Department of Justice announced a plan to reclassify bump stocks as "machineguns" under existing federal law, effectivelyMachineguns manufactured after May 1986 are illegal on the federal level, but pre-1986 ones remain legal in most states and are highly regulated. Since bump stocks were not invented until 2010, all existing supplies effectively become illegal if classified as a machinegun. banning them nationwide. Only two states had banned bump stocks prior to the Las Vegas shooting. The final rule of the DoJ was issued on December 18, 2018. Now, , bump stocks are illegal for almost all US civilians, but multiple lawsuits are pending that challenge that rule. In May 2019, the Offensive Weapons Act 2019 prohibited bump stocks in the UK.

Public opinion

Immediately following the 2017 Las Vegas shooting, 72% of registered voters supported a bump stock ban, including 68% of Republicans and 79% of Democrats. A 2018 poll found 81% of American adults supported banning bump stocks with a margin of error of ±3.5%. A different poll around the same time found 56% of American adults supported banning bump stocks with a margin of error of ±4%.

Regulatory status in the United States

Federal

The ATF ruled in 2010 that bump stocks were not a firearm subject to regulation and allowed their sale as an unregulated firearm part. In the 2017 Las Vegas shooting, twelve bump stocks were found at the scene. The National Rifle Association stated on October 5, 2017, "Devices designed to allow semi-automatic rifles to function like fully-automatic rifles should be subject to additional regulations", and called on regulators to "immediately review whether these devices comply with federal law". The 2017 shooting generated bipartisan interest in regulating bump stocks. On October 4, 2017, Senator Dianne Feinstein introduced a bill to ban bump stocks, but it was not acted upon. Instead, on February 20, 2018, President Trump instructed the ATF to issue regulations to treat bump stocks as machineguns.

President Donald Trump blamed former President Barack Obama for having "legalized bump stocks", which he termed a "BAD IDEA",Dan Merica.

. CNN, March 23, 2018. Accessed March 10, 2021. a claim which was found to be partly erroneous by ''USA Today''. On March 23, 2018, at President Trump's request the Department of Justice announced a plan to ban bump stocks at the federal level. The proposed change would reclassify bump stocks as "machineguns" and effectively ban the devices in the United States under existing federal law. A notice of proposed rulemaking was issued by the ATF on March 29, 2018, and opened for public comments. Over 119,000 comments were submitted in support of the proposed rule, while over 66,000 comments expressed opposition to it. On December 18, 2018, the final regulation to ban bump stocks was issued by the Department of Justice and published in the ''Federal Register'' on December 26.Bump-Stock-Type Devices
83 Fed. Reg. 66,514 (Dec. 26, 2018). The final rule states that "bump-stock-type devices" are covered by the Gun Control Act, as amended, which with limited exceptions, makes it unlawful for any person to transfer or possess a machinegun unless it was lawfully possessed prior to 1986. Since the bump-stock-type devices covered by this final rule were not in existence prior to 1986, they would be prohibited when the rule becomes effective. The ban went into effect on March 26, 2019, by which owners of bump stocks were required to destroy them or surrender them to ATF, punishable by 10 years imprisonment and a $250,000 fine.

State

Prior to the federal ban effective March 26, 2019, some states had taken action on their own to restrict ownership of the accessory. Since 1990, the sale of bump stocks has been illegal in California. They were banned in New York with the passage of the NY SAFE Act in 2013, and more explicitly banned in early 2019. The device's legal status is unclear in Connecticut, Michigan, Minnesota, and Puerto Rico.

After the 2017 Las Vegas shooting

In his final day as governor in January 2018, New Jersey Governor Chris Christie signed legislation making the gun accessory illegal in New Jersey. Massachusetts banned bump stocks after the 2017 Las Vegas shooting.

In March 2018, following the Stoneman Douglas High School shooting, Florida enacted SB 7026, which, among other things, banned bump stocks. The portion of the legislation banning bump stocks took effect in October 2018; possession in Florida is a third-degree felony. Vermont passed a similar law in 2018, which went into effect in October 2018; possession in Vermont is a misdemeanor. Delaware, Hawaii, Maryland, Washington, Washington D.C., and Nevada have also banned bump stocks.

Some states that do not ban bump stocks may have localities that ban them, such as Northbrook, Illinois (April 2018); Boulder, Colorado (May 2018); and others.

Federal lawsuits

Several gun rights groups have challenged the federal regulation.

Gun Owners of America

In December 2018, Gun Owners of America sued the federal government in the U.S. District Court for the Western District of Michigan, challenging the bump stock ban. On March 21, 2019, the group's request for a preliminary injunction was denied by the district court. The U.S. Court of Appeals for the Sixth Circuit and U.S. Supreme Court both denied a stay on the effective date of the regulation pending the appeal.

Following oral argument in December 2020, the Sixth Circuit panel issued a 2–1 ruling in favor of the plaintiffs on March 25, 2021.
Gun Owners of America, Inc. v. Garland
', 992 F.3d 446 (6th Cir. 2021). The majority decision, written by Judge Alice M. Batchelder and joined by Judge Eric E. Murphy, ruled that (1) an agency's interpretation of a criminal statute is not entitled to ''Chevron'' deference, (2) bump stocks cannot be classified as machineguns, thus the ATF's rule is not the best interpretation of the law, and (3) the plaintiffs are likely to prevail in their challenge, therefore the district court should have granted an injunction. The court remanded the case back to the district court for proceedings in accordance with its opinion (i.e., to issue an injunction).Brian Flood
Federal Bump Stock Ban Blocked by Divided Appeals Court
Bloomberg Law, March 25, 2021. Accessed March 26, 2021. Judge Helene White dissented, writing that the Supreme Court had previously applied ''Chevron'' deference to agency interpretations of criminal statutes in the cases of '' Babbitt v. Sweet Home Chapter of Communities for a Great Oregon'' and '' United States v. O'Hagan''. The appeals court granted an en banc petition on June 25, 2021 and heard oral argument in October 2021. On December 3, 2021, the court issued an 8-8 split decision, thus leaving the district court's denial of a preliminary injunction in place. The Supreme Court declined to hear the case on October 3, 2022.

Guedes (Firearms Policy Coalition) and Codrea

The Firearms Policy Coalition and other gun-rights groups sued in the federal district court in Washington, D.C., also seeking an injunction. In February 2019, U.S. District Judge Dabney L. Friedrich denied the Firearms Policy Coalition's request for an injunction, determining that the group had not put forward convincing legal arguments that the ban was invalid. The U.S. Court of Appeals for the D.C. Circuit stayed the effective date of the regulation, but only as applied to the plaintiffs and their members.
Guedes v. Bureau of Alcohol, Tobacco, Firearms and Explosives
', 920 F.3d 1 (D.C. Cir. 2019). A broader injunction was denied by the Supreme Court.

On April 1, 2019, the D.C. Circuit affirmed the district court's denial of a preliminary injunction in a ''per curiam'' decision, based largely on ''Chevron'' deference. The decision allowed the ban to go into effect for the plaintiffs. Judge Karen L. Henderson issued an opinion concurring in part and dissenting in part. A second stay application was denied by the Supreme Court on April 5, 2019, with Thomas and Gorsuch indicating that they would have granted the application. The Supreme Court denied a petition for a writ of certiorari (petition for review) on March 2, 2020; Gorsuch issued a statement agreeing that the time was not right for Supreme Court review, but criticizing the D.C. Circuit's position and writing that "''Chevron''s application in this case may be doubtful."

The case then returned to the district court on the merits, and in February 2021, the court granted summary judgment in favor of the government, holding that ''Chevron'' deference applied; that ATF had the authority to state that the NFA's definition of "machinegun" includes bump stocks; and that ATF's interpretation of the statutory language was reasonable. The court also rejected the plaintiffs' Taking Clause and Ex Post Facto Clause claims, as well as their claim that the underlying statutes were impermissibly vague. On August 9, 2022, the D.C. Circuit Court of Appeals upheld the ban by reasoning that it was the best reading of the law without applying ''Chevron'' deference.

Aposhian and Cargill

In 2019, W. Clark Aposhian, the chairman of the Utah Shooting Sports Council, a gun rights group, sued the ATF in the federal district court of Utah over the bump stock ban, arguing that the promulgation of the regulation exceeded the ATF's statutory authority. Aposhian is represented by the New Civil Liberties Alliance.Dennis Romboy

''Deseret News'' (January 27, 2021). The district court denied the plaintiffs' request for a preliminary injunction to block the ban in March 2019. In March 2019, the U.S. Court of Appeals for the Tenth Circuit granted a temporary stay that applies only to the plaintiff, but ultimately upheld the denial of a preliminary injunction.Amanda Pampuro
10th Circuit Backs Out of Opening Phase of Fight Over Bump Stock Ban
Courthouse News Service (March 5, 2021). In April 2019, in a divided opinion, the Tenth Circuit denied the motion for a stay, and a divided panel upheld the district court's ruling. The appeals court granted review ''en banc'' (i.e., by the full court), but ultimately dismissed the grant of ''en banc'' rehearing as improvidently granted, allowing the panel decision (and thus the bump-stock ban) to stay in place. The Supreme Court declined to hear the case on October 3, 2022.

An Austin, Texas gun rights activist, Michael Cargill, sued ATF in 2019, in the U.S. District Court for the Western District of Texas, similarly challenging the authority of the agency to classify bump stocks as illegal machine guns. Cargill is also represented by the New Civil Liberties Alliance. The district court dismissed the suit in November 2020. On December 14, 2021, a unanimous three judge panel on the U.S. Court of Appeals for the Fifth Circuit upheld the ban. On June 23, 2022, the court vacated the decision and took the case en banc. Oral argument was heard on September 12, 2022. On January 6, 2023, the court ruled that bump stocks are not machineguns and reversed the district court.

Takings Clause lawsuits

In June 2018, the group Maryland Shall Issue filed a putative class action lawsuit in the federal district court in Maryland, challenged 2018 Maryland Senate Bill 707 which banned "rapid-fire trigger activators"; the plaintiffs alleged that the ban was an unconstitutional taking requiring just compensation, among other challenges. In November 2018, the district court dismissed the case. In June 2020, the U.S. Court of Appeals for the Fourth Circuit affirmed the dismissal of the suit in a 2–1 vote. In May 2021, the Supreme Court declined to hear the case.

Two similar lawsuits were filed in the United States Court of Federal Claims challenging the federal bump-stock ban—one filed by bump stock owners (McCutchen), the other by bump-stock suppliers (Modern Sportsman and RW Arms). Both were dismissed.Jake Charle
Litigation Highlight: No Compensation for Bump Stock Owners
Duke Center for Firearms Law (October 25, 2019). In the latter case, the court held that the ATF Final Rule banning bump stocks "was promulgated pursuant to the police power to protect public safety and therefore not a compensable taking under the Fifth Amendment." Both cases were unsuccessfully appealed to the Court of Appeals for the Federal Circuit. En banc petitions were denied and the Supreme Court denied review.

In another case, filed in the District Court for the Northern District of Texas, the government failed to have the case dismissed, but was given another opportunity to argue so. However, the case is now stayed pending the outcome of McCutchen and Modern Sportsman.

Another challenge, filed in the District Court for the Western District of Kentucky, was unsuccessful. The Sixth Circuit Court of Appeals will hear the case on January 19, 2023.

John Doe

A class action lawsuit filed in the U.S. District Court for the Southern District of Illinois seeking immunity for legal purchasers of bump stocks prior to the ATF rule change was denied by the court in June 2020. On October 31, 2022, the United States Court of Appeals for the Federal Circuit upheld the ban.

US v Alkazahg

The Navy-Marine Corps Court of Criminal Appeals ruled on September 7, 2021 that a bump stock does not fall under the definition of a machinegun. The ruling was not appealed by the government.

State lawsuits

Florida

Florida banned bump stocks in October 2018. A class action lawsuit challenging the ban as an unconstitutional taking requiring just compensation was unsuccessful in the Leon County circuit court in May 2019 and in the 1st District Court of Appeal in January 2021.

Patent infringement suit

Slide Fire Solutions filed suit against Bump Fire Systems for infringement of its patents on bump stock designs in 2014. The suit alleged that Bump Fire Systems infringed eight US Patents, for example, United States Patent No. 6,101,918 entitled "Method And Apparatus for Accelerating the Cyclic Firing Rate of a Semi-Automatic Firearm" and United States Patent No. 8,127,658 entitled "Method of Shooting a Semi-Automatic Firearm". The suit was settled in 2016, resulting in Bump Fire Systems ceasing manufacture of the product in contention.

Other lawsuits

Survivors of the 2017 Las Vegas shooting sued bump stock patent holder and manufacturer Slide Fire Solutions, claiming the company was negligent and that they deliberately attempted to evade U.S. laws regulating automatic weapons: "this horrific assault would not and could not have occurred, with a conventional handgun, rifle, or shotgun, of the sort used by law-abiding responsible gun owners for hunting or self defense." The suit was dismissed in September 2018; the court determined that the bump stocks of the sort used by gunman Stephen Paddock to commit the murders, were "firearm components" rather than "firearm accessories" and were therefore subject to the Protection of Lawful Commerce in Arms Act (PLCAA), a federal law immunizing manufacturers and sellers of firearms from liability for harm "caused by those who criminally or unlawfully misuse firearm products".Order
