SMITH, Senior Judge

Today, the Court addresses the cross-motions for summary judgment filed by plaintiffs RW Arms, Ltd., Mark Maxwell, and Michael Stewart (collectively, “RW Arms”) and plaintiff- intervenors Slide Fire Solutions, LP (“Slide Fire”) and Jeremiah Cottle. See ECF Nos. 92, 93. This case relates to the 2019 ban on bump stocks and its invalidation in Garland v. Cargill, 602 U.S. 406 (2024). In March 2019, the Bureau of Alcohol, Tobacco, Firearms, and Explosives (“ATF”) destroyed approximately 73,000 bump stocks possessed by RW Arms. RW Arms filed suit and sought just compensation for their value. An ensuing title dispute arose as Slide Fire and Cottle intervened to claim ownership of the bump stocks. For the foregoing reasons, the Court GRANTS plaintiff-intervenors Slide Fire and Jeremiah Cottle’s motion for partial summary judgment and DENIES plaintiff RW Arms’ motion for summary judgment.

I. Background

A. Slide Fire Shuts Down

The Court provided a more extensive history of the case in a prior opinion, familiarity with which is assumed. See Modern Sportsman LLC v. United States (“Modern Sportsman III”), 176 Fed. Cl. 567, 575 (2025). This opinion provides a recount of the facts relevant to resolving the current dispute over title to the bump stocks.

On October 1, 2017, a gunman opened fire on a crowd in Las Vegas, Nevada, using semi- automatic rifles upgraded with bump stocks. Bump stocks replace the standard stocks on rifles, which enable users to fire their weapons more rapidly. Pl.’s Mot. for Summary Judgment, ECF No. 92-1 at 3 [hereinafter “RW Arms Mot.”]. The shooting prompted public scrutiny and political debate regarding bump stocks legality, much of which was directed at Jeremiah Cottle. Id.

Jeremiah Cottle invented bump stocks and founded Slide Fire, which manufactures and sells them. Id. at 3–4. After the Las Vegas shooting, Cottle received death threats and became concerned about his safety and that of his family. Id. at 4.

Around March 2018, the United States Department of Justice announced it would reclassify bump stocks as machine guns and ban them under the National Firearms Act of 1934 (“NFA”). Id. This news combined with the threats on Cottle, led him to wind down Slide Fire’s operations and move to Tennessee. Id. at 4–5. By May 2018, Slide Fire shut down its website, ceased taking orders, and gave up its federal firearms license. Id.

B. Operations of RW Arms

As Slide Fire shutdown, then-employees Mark Maxwell and Michael Stewart approached Cottle with a proposal to start their own retail firearms business. Id. Their business, RW Arms, would market and sell Slide Fire’s remaining inventory of bump stocks until the ban took effect. Id. Slide Fire would transfer its bump stock inventory to RW Arms and split the proceeds from each sale evenly. Id. This handshake agreement was never reduced to writing. Id.; Pl.-Intervenor’s Mot. for Partial Summary Judgement, ECF No. 93, at 2 [hereinafter “Slide Fire Mot.”].

2 Once Slide Fire ceased sales, RW Arms stored and sold the bump stocks from its Fort Worth, Texas warehouse and remitted fifty percent of the proceeds to Slide Fire and Cottle as agreed. RW Arms Mot. at 5–6. Initially, the checks were addressed to Slide Fire but eventually were sent to Cottle individually. Id. at 6.

C. Bump Stock Destruction

On December 26, 2018, the ATF published its Final Rule (“the Rule”) Bump-Stock-Type Devices, 83 Fed. Reg. 66,514 (Dec. 26, 2018). In effect, the Rule retroactively redefined bump stocks as machine guns under the NFA and the Gun Control Act. RW Arms Mot. at 9. The Rule imposed a national ban on the sale, possession, and transfer of bumps stocks, and required owners to surrender or destroy such devices by March 26, 2019. Id.

Soon after, the ATF visited RW Arms’s Fort Worth warehouse to inspect its inventory of bump stocks and discovered that destroying them would require an industrial shredder. Id. Maxwell contacted American Shredder to destroy the stocks and hired a third party to film the destruction. Id.

On March 26, 2019, RW Arms transported the stocks to American Shredder for destruction. Id. at 10. Cottle attended the destruction, along with personnel from the ATF and Stewart and Maxwell. Id. at 11; Slide Fire’s Mot. at 14. The ATF signed invoices on RW Arms letterhead for the destroyed stocks. RW Arms Mot. at 11. RW Arms also paid the $7,000 invoice from American Shredder but subtracted $3,500 from the next payment to Cottle. Id. at 10; Pl. Intervenor’s Response to Mot. Sum. J., ECF No. 97, at 11 [hereinafter “Slide Fire Resp.”].

D. The Litigation Agreement between Slide Fire and RW Arms

Around this time, Maxwell, Stewart, and Cottle met to discuss whether to the destruction constituted a compensable taking under the Fifth Amendment of the United States Constitution. RW Arms Mot. at 12. Cottle would not join the potential lawsuit, but the parties would split any recovery fifty-fifty. Id. This agreement was reduced to writing. Id.; Slide Fire Resp. at 12–13. Following the discussions, RW Arms filed suit in this Court and Stewart appraised Cottle as their case progressed. RW Arms Mot. at 13. When the Rule was invalidated in Cargill, Cottle considered reopening Slide Fire. Id.

II. Procedural History

The Modern Sportsman, LLC (“Modern Sportsman”), the original plaintiff in this matter, filed its complaint on March 26, 2019. Pl. Compl., ECF No. 1. In its initial option, the Court concluded that ATF properly exercised its police powers when it enacted the Rule and dismissed the case. See Modern Sportsman, LLC v. United States (“Modern Sportsman I”), 145 Fed. Cl. 575, 583 (2019), aff’d 2021 WL 4486419 (Fed. Cir. 2021). Specifically, the Court found that the “Final Rule’s mandate to surrender or destroy bump stocks does not satisfy the public use requirement under a Fifth Amendment Takings analysis, and that ATF appropriately acted within the confines of the police power.” Id. at 580–81. However, the Supreme Court in a related matter invalidated the Rule and overturned the bump stock ban in June 2024. Cargill, 602 U.S. 406 (2024).

3 After Cargill, Modern Sportsman filed a motion for relief from judgment of the original dismissal and request for leave to file an amended complaint which the Court granted. Order Granting Pl. Mot. for Relief from J., ECF No. 30.

RW Arms, Stewart, and Maxwell then filed their second amended complaint, asserting takings and illegal exaction claims. See Pl.’s Second Amended Compl., ECF No. 31 at ¶¶ 36–64. RW Arms claimed it “legally purchased and owned” the bump stocks destroyed by the ATF. See id. at ¶ 14.
