SB1283 adds a new statutory category—“less‑than‑lethal projectile device”—to 18 U.S.C. §921(a) and inserts that phrase into the statutory provision that defines covered firearms. The bill sets out mechanical and functional criteria for the category and instructs the Attorney General to make a classification determination upon request.
This matters because it creates a clear pathway for designers and sellers of kinetic‑impact and other non‑lethal devices to seek a federal determination that their products are not subject to the federal firearms regime. The statutory tests (design intent, velocity, and feeding‑mechanism limits) plus a 90‑day DOJ review deadline will reshape compliance planning for manufacturers, procurement by public safety agencies, and how federal regulators and prosecutors treat these tools.
At a Glance
What It Does
The bill amends 18 U.S.C. §921(a) to add an explicit category for “less‑than‑lethal projectile devices,” sets objective criteria for that category, and requires the Attorney General to decide whether a submitted device meets the definition within 90 days. The change places those devices outside the scope of the referenced federal firearms definition when the criteria are met.
Who It Affects
Manufacturers, importers, and distributors of kinetic‑impact and other non‑lethal projectile systems; federal regulators (DOJ/ATF) who will perform the determinations; and law enforcement and private purchasers who may change procurement or training policies based on classification outcomes.
Why It Matters
By converting uncertainty into a statute and a formal review process, the bill lowers legal risk for some innovators and buyers but also shifts practical responsibility to DOJ to make technically complex judgments quickly—and potentially creates legal gray areas about borderline designs and conversions.

What This Bill Actually Does
SB1283 works by changing the statutory definition framework that currently determines whether a device counts as a “firearm” under federal law. Instead of leaving novel kinetic and less‑lethal technologies to case‑by‑case enforcement or guidance, the bill inserts an explicit carveout: devices that meet the bill’s three‑part test are treated separately from the firearms definitions in Title 18.
The test itself is mechanical and functional. First, the device must not be designed to expel, and must not be readily convertible to accept, ammunition commonly used in handguns, rifles, or shotguns, nor to discharge any projectile at a velocity over 500 feet per second.
Second, the device must be designed and intended to be used in a way that is not likely to cause death or serious bodily injury. Third, the device must not accept, and must not be readily modifiable to accept, certain kinds of ammunition feeding devices—specifically those loaded through the inside of a pistol grip or feeding mechanisms commonly used in semiautomatic firearms.
Those three criteria together create a statutory boundary between conventional firearms and a defined class of less‑lethal devices.Practically, the bill creates a process: a person (manufacturer, seller, or other stakeholder) can send a device to the Attorney General and request a determination whether it meets the definition. The Attorney General must issue that decision within 90 days of receiving the device.
That requirement forces DOJ to develop technical review capacity and interpretive criteria, and it gives businesses a predictable, time‑bounded path to a federal classification that will inform compliance, sales, and procurement choices.The bill does not itself prescribe labeling, testing protocols, or approval fees; it limits itself to the statutory definition and a deadline for the Attorney General’s decision. It therefore places the burden on DOJ to define how submissions will be handled in practice, what evidentiary standard will govern “designed and intended” uses, and how to treat borderline or convertible devices—questions the statute leaves to agency implementation.
The Five Things You Need to Know
The bill adds a new paragraph (numbered as a distinct subsection) to 18 U.S.C. §921(a) creating the term “less‑than‑lethal projectile device.”, It sets a hard velocity cutoff: the device may not discharge projectiles at a velocity exceeding 500 feet per second to qualify for the exemption.
The statutory test requires that the device not be designed to accept—or be readily convertible to accept—ammunition commonly used in handguns, rifles, or shotguns.
The device must not accept, and must not be readily modifiable to accept, an ammunition feeding device loaded through the inside of a pistol grip or feeding devices commonly used in semiautomatic firearms.
The Attorney General must make a written determination about whether a submitted device satisfies the definition within 90 days of receiving the device.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Textual insertion creating the exemption reference
This provision inserts the phrase “or a less‑than‑lethal projectile device” into the second sentence of paragraph (3) of §921(a). In practice that places the new category alongside existing defined terms in the firearms statute, signaling that devices meeting the forthcoming definition are treated differently for the purposes of Title 18. The change is narrowly textual: it doesn’t enumerate the downstream statutory consequences, but by altering the definition section it directly affects how other provisions that rely on §921(a) will apply.
Velocity and ammunition conversion limits
Subclause (i) spells out two connected limits: the device must not be designed or readily convertible to accept conventional handgun, rifle, or shotgun ammunition, and it must not be able to discharge any projectile above 500 feet per second. Those dual criteria mix an objective kinetic threshold (500 fps) with the convertible‑ammunition test, which targets weapon frames or barrels that can be repurposed to fire lethal rounds.
Safety/intent requirement
Subclause (ii) requires that the device be designed and intended for use that is not likely to cause death or serious bodily injury. That introduces a subjective element—‘designed and intended’—which will require DOJ to develop an evidentiary standard for manufacturer intent, marketing, and engineering assessments when making determinations.
Feeding‑mechanism prohibition
Subclause (iii) disqualifies devices that accept, or can be readily modified to accept, certain feeding devices—specifically those loaded through the inside of a pistol grip or feeding devices commonly used in semiautomatic firearms. This targets designs that could be adapted to high‑rate or magazine‑style feeding, closing a practical conversion route that would otherwise blur the line between non‑lethal and conventional firearms.
Attorney General review timeline
This clause creates a submission pathway and deadline: an interested person may send a device to the Attorney General and request a classification, and the Attorney General must render a determination within 90 days after receiving the device. The provision is procedural rather than substantive: it does not specify fees, required documentation, or appeal rights, leaving those implementation details to DOJ rulemaking or internal procedures.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Manufacturers and startups designing less‑than‑lethal kinetic devices — They gain a statutory pathway to secure a federal classification that can reduce regulatory uncertainty and support marketing and procurement decisions.
- Public safety agencies and law enforcement buyers — Agencies can seek determinations before purchasing, reducing legal risk around procurement of unconventional devices and enabling quicker adoption of new tools if cleared.
- Private security firms and institutional purchasers — A federal classification may lower compliance costs and background‑check concerns that attach to items treated as firearms, simplifying purchasing and training decisions.
Who Bears the Cost
- Department of Justice (and ATF operationally) — DOJ must build review capacity, develop technical criteria, and issue timely written determinations; that work implies staff time, lab testing, and policy drafting that are not funded in the statute.
- Manufacturers of borderline or convertible designs — Companies with products near the statutory thresholds may face uncertainty, submission costs, and possible market disruption while awaiting DOJ determinations.
- Retailers and distributors — Until DOJ issues determinations, sellers will face legal ambiguity about whether particular devices are subject to federal firearms controls, potentially chilling sales or exposing businesses to enforcement risk.
Key Issues
The Core Tension
The bill’s central dilemma is between encouraging safer, non‑lethal innovation through a predictable statutory carveout and avoiding creation of regulatory loopholes that let lightly regulated devices produce lethal outcomes; it solves legal uncertainty for innovators but forces DOJ to make high‑stakes technical judgments and leaves open whether the statutory tests capture the real‑world lethality of borderline designs.
The bill sets mechanical and functional gates (velocity, ammunition acceptability, feeding mechanism) alongside an intent‑based safety test, but it leaves critical procedural and evidentiary questions to DOJ. The statute does not define how a submitter proves “designed and intended” non‑lethality, whether DOJ determinations are binding on other federal actors, or whether an adverse classification can be administratively appealed.
It also omits any testing protocols, sampling rules, or fee structure for submissions, so agencies will need to translate statutory language into operational guidance that balances speed with technical rigor.
The 500 feet‑per‑second threshold is an administrable bright line but it measures velocity rather than kinetic energy or impact effect; that choice creates edge cases (light projectiles at high speed vs. heavy projectiles at lower speed) and incentives for designers to optimize around the statutory metric. Likewise, the “readily converted” language will trigger fact‑intensive conversion analyses: small design changes could flip a device in or out of the exemption, exposing firms and regulators to litigation testing the statutory criteria.
Finally, because the statute focuses on Title 18 classification, it does not preempt state or local rules that may treat the same devices differently, producing a patchwork of regulatory outcomes.
