The Keep Americans Safe Act amends federal firearms law to define and broadly prohibit large capacity ammunition feeding devices (LCAFDs) — magazines, drums, belts, helical devices, and similar items that accept or can readily be converted to accept more than 15 rounds. The bill makes it unlawful to import, manufacture, sell, transfer, or possess LCAFDs in or affecting interstate or foreign commerce, while carving out several narrow exemptions and grandfathering devices lawfully possessed on enactment.
Practically, the bill adds mandatory engraved serial and manufacture-date markings for devices made after enactment, extends seizure and forfeiture to include these devices, folds violations into existing federal firearms penalties, and explicitly allows Byrne grant funds to pay for buy-back compensation. For compliance officers and firearm manufacturers, the act creates new marking and recordkeeping obligations; for law enforcement and campus police it preserves targeted exceptions; for local governments it opens a federal funding route for buybacks.
At a Glance
What It Does
The bill defines a 'large capacity ammunition feeding device' as any magazine, belt, drum, feed strip, helical device, or similar device that holds, or can be readily converted to hold, more than 15 rounds, and then criminalizes importing, manufacturing, selling, transferring, or possessing such devices in or affecting interstate or foreign commerce. It requires serial numbers and manufacture dates on devices produced after enactment, adds these devices to seizure/forfeiture rules, and attaches existing federal firearms penalties to violations.
Who It Affects
Licensed firearm manufacturers and importers (who must mark devices and who can retain limited testing exemptions), commercial sellers, private owners acquiring or possessing devices after enactment, campus and other qualified law enforcement officers (who are expressly exempt), and state and local jurisdictions that run buy-back programs funded by Byrne grants.
Why It Matters
This bill shifts regulatory focus from particular firearms to the ammunition-feeding component that increases sustained fire capability; it creates a legal regime to remove such devices from circulation while preserving law-enforcement and narrowly tailored operational exceptions. The serial-marking rule and seizure language also change evidence and tracing dynamics for post-enactment devices.

What This Bill Actually Does
The core of the bill is a new definition and a near-total ban. It inserts into 18 U.S.C. § 921 a definition of a 'large capacity ammunition feeding device' that covers common and uncommon feeding mechanisms — magazines, drums, belts, helical feeds, and devices coupled together — whenever they hold, or can be readily restored or converted to hold, more than 15 rounds.
The statutory draft expressly excludes only tubular devices designed solely for .22 rimfire ammunition. Once defined, the bill amends § 922 to make it unlawful to import, manufacture, sell, transfer, or possess these devices in or affecting interstate or foreign commerce.
The prohibition is subject to a set of exceptions. It does not apply to devices lawfully possessed on the date of enactment (a grandfather clause).
It preserves standard government and law-enforcement exceptions: the United States and its agencies, state and local governments, qualified law enforcement officers (as cross-referenced to § 926B), and a narrowly drawn campus law-enforcement category provided that campus officers meet specific duties and recognition criteria. The bill also authorizes exceptions for atomic energy licensees for site physical protection and for licensed manufacturers/importers that hold devices for Attorney General–authorized testing or experimentation.
It includes a limited path for retired law-enforcement officers to keep devices that their agencies sold or transferred to them upon retirement or that they obtained for official use prior to retirement.On identification and enforcement, the bill amends § 923(i) to require that any LCAFD manufactured after enactment be engraved or cast with a serial number and the manufacture date, plus any additional markings the Attorney General prescribes by regulation. It then adjusts seizure and forfeiture (§ 924(d)) and penalty provisions (§ 924(a)) so that LCAFDs are treated the same as firearms and ammunition for purposes of forfeiture and criminal penalties.
Finally, the bill amends the Byrne grant statute to permit use of funds to compensate owners in buy-back programs for surrendered LCAFDs, and it contains a severability clause to preserve the remainder if any part is held unconstitutional.
The Five Things You Need to Know
The bill defines a 'large capacity ammunition feeding device' as any device that accepts, or can be readily restored, changed, or converted to accept, more than 15 rounds; the definition expressly includes coupled devices and helical feeders and excludes only tubular .22 rimfire devices.
It makes it a federal offense to import, manufacture, sell, transfer, or possess such devices 'in or affecting interstate or foreign commerce,' subject to statutory exemptions and grandfathering for devices lawfully possessed on enactment.
Devices manufactured after the date of enactment must bear a legible, conspicuous serial number and the date of manufacture engraved or cast on the device, with additional identification requirements delegated to the Attorney General.
The bill amends federal seizure and forfeiture law to permit forfeiture of LCAFDs and folds violations into existing federal firearms penalties under 18 U.S.C. § 924.
Section 501(a)(1) of the Byrne grant program is amended to explicitly allow grant funds to compensate people who surrender LCAFDs under buy-back programs.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
States that the Act may be cited as the 'Keep Americans Safe Act.' This is a pure caption and creates no operative obligations, but it frames the bill’s policy goal in legislative text.
Defines 'large capacity ammunition feeding device' and 'qualified law enforcement officer'
Adds a new paragraph to the statutory definitions. The LCAFD definition is purposefully broad — it covers common magazines and other feeding mechanisms and extends to devices that can be 'readily restored, changed, or converted' to accept more than 15 rounds. The only explicit exclusion is for tubular devices designed solely for .22 rimfire. The section also brings 'qualified law enforcement officer' into this statute by cross-reference to § 926B, which is used in the exemptions that follow. The 'readily converted' language will be central to enforcement but is not further defined here.
Prohibits commerce and possession, with enumerated exemptions
Creates a new subsection making it unlawful to import, sell, manufacture, transfer, or possess LCAFDs in or affecting interstate or foreign commerce. The subsection contains multiple carve-outs: (1) a grandfather clause protecting devices lawfully possessed on enactment; (2) exemptions for federal and state governments and for qualified law enforcement officers (including campus officers meeting specific criteria); (3) an exemption for atomic energy licensees for onsite physical protection and related personnel for training/transport; (4) an exemption permitting retired law-enforcement officers to possess devices that agencies transferred to them upon retirement or that they obtained for official use before retiring; and (5) a testing/experimentation exemption for licensed manufacturers/importers under Attorney General authorization. Practically, these exemptions preserve operational capabilities for certain government uses while removing civilian commerce in these devices.
Requires serial number and manufacture date on post-enactment devices
Mandates that any LCAFD manufactured after enactment must be legibly and conspicuously engraved or cast with a serial number and the date it was made, and allows the Attorney General to require additional identification by regulation. This creates a downstream traceability regime for newly produced devices but does not retroactively alter unmarked grandfathered devices.
Adds LCAFDs to seizure and forfeiture provisions
Modifies federal forfeiture language to include LCAFDs alongside firearms and ammunition. This means law-enforcement seizures of these devices tied to criminal activity can be subject to civil forfeiture and the devices treated as contraband in forfeiture proceedings, changing evidentiary and disposal pathways for seized items.
Attaches existing federal penalties to violations
Amends the cross-reference in the criminal penalty statute to include the new prohibition, so that violations of § 922(v) carry the same fines and imprisonment terms applicable to comparable firearms offenses under § 924(a). The bill does not create a new sentencing scheme; it imports current penalties.
Allows Byrne grant funds for buy-back compensation
Adds a specific authorization to the Byrne grant statute permitting use of grant funds to compensate owners who surrender LCAFDs in buy-back programs. This gives state and local jurisdictions an explicit federal funding source for buybacks they choose to run, though it does not appropriate additional funds or detail program design.
Severability
Provides that if any provision is held unconstitutional, the remainder of the Act stays in force. This is a standard clause intended to preserve operative sections if a court strikes one down.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Local governments and public-safety officials running buy-back programs — the bill explicitly authorizes Byrne grant funds to pay compensation, lowering the fiscal barrier to organized collection efforts.
- Law enforcement agencies and active campus police — the statute preserves exemptions allowing agencies and qualified officers to obtain, possess, and use LCAFDs for official duties, including site security exceptions for nuclear facilities.
- Crime victims and communities seeking reduced availability of high-capacity feeding devices — by targeting the feeding device rather than a particular firearm, the law aims to reduce the availability of accessories that enable sustained fire.
- Federal investigators and crime laboratories — serial marking of post-enactment devices improves traceability for newly manufactured devices used in crimes, aiding investigations and linking devices to sources.
Who Bears the Cost
- Firearm and accessory manufacturers and importers — they must apply serial numbers and manufacture dates to new devices, adapt production processes, and manage any AG-prescribed additional identification requirements.
- Retailers and secondary-market sellers — the prohibition on commerce will reduce legal inventory and sales opportunities for LCAFDs and require compliance screening to avoid illegal transfers.
- Private individuals acquiring LCAFDs after enactment — those who obtain devices post-enactment face criminal exposure; owners who possess grandfathered devices may still face market limitations and reduced resale options.
- State and local law enforcement and courts — enforcement and forfeiture will generate administrative, testing, and litigation burdens; prosecutors and courts must process offenses, and civil-forfeiture actions may increase caseloads without new appropriations.
Key Issues
The Core Tension
The central dilemma is between removing devices that materially increase sustained-fire capacity — a public-safety goal — and creating a regulatory regime that respects prior ownership, preserves law-enforcement needs, and remains administrable: broad prohibitions plus grandfathering and multiple exemptions reduce political and operational resistance but generate enforcement uncertainty, tracing gaps, and compliance burdens for manufacturers and courts.
The bill relies on several draft-dependent concepts that will drive implementation complexity. First, the 'readily restored, changed, or converted' trigger in the definition is fact-intensive and will require either regulatory clarification or case-by-case technical analysis; manufacturers of convertible devices and prosecutors will both face uncertainty until the Attorney General or courts define the threshold for 'readily.' Second, serial-numbering applies only to devices manufactured after enactment, so a large stock of grandfathered, unmarked devices will remain in private hands; tracing and enforcement therefore bifurcate into marked post-enactment devices and unmarked pre-enactment devices, complicating investigations and market dynamics.
Operationally, the exemptions create lines that are hard to police. The retired-officer exception (for devices sold or transferred by an agency upon retirement, or previously procured for official use) depends on agency practices and recordkeeping; without robust transfer documentation, proving lawful retention could be contested.
The interstate-or-foreign-commerce hook for criminalization is broad and will raise evidentiary questions where possession is purely intrastate absent a demonstrated commerce nexus. Finally, authorizing Byrne funds for buybacks lowers a funding hurdle but does not appropriate money or provide program standards, meaning uptake and uniformity across jurisdictions will vary and may create uneven mitigation of the remaining unregulated stock.
