Winchester is one of the most storied names in American firearms history.
It is also, today, not one company at all.
Ammunition sold under the Winchester name comes from a completely different owner than Winchester branded firearms.
That split traces back decades and explains most of the confusion shoppers run into.
Knowing which Winchester you are asking about changes the entire answer to where it is made.
This article separates the ammunition business from the firearms business, covers the plants behind each, and looks at what stays domestic and what does not.
So let’s get started.

Where Is Winchester Made?
Winchester Ammunition, owned by Olin Corporation, makes its shells and cartridges in East Alton, Illinois, Oxford, Mississippi, and Manitowoc, Wisconsin.
All three of those plants sit inside the United States.
Winchester branded firearms are a different story. They are produced under license by the FN Browning Group, primarily out of Browning’s Utah operations and FN Herstal’s plants in Belgium and Portugal.
Both businesses trace back to the original Winchester Repeating Arms Company, but a 1980s bankruptcy split the name into two separate lineages.
Who Owns Winchester?
The official Winchester Ammunition site, winchester.com, is a good place to start untangling the ownership picture.
Winchester Ammunition is a division of Olin Corporation, a publicly traded chemicals and materials company.
Winchester firearms come from an entirely different corporate family tied to FN Herstal and Browning.
The two businesses share a name and a logo, but not an owner, a supply chain, or a factory floor.
Where Did Winchester Come From?
Both modern Winchester businesses trace back to the original Winchester Repeating Arms Company.
That company eventually filed for bankruptcy, which split its legacy in two.
The ammunition side and the firearms side went their separate ways from that point forward, and they never fully reunited.
Where Does Olin Make Winchester Ammunition?
Olin’s Winchester division runs its oldest and largest ammunition plant in East Alton, Illinois.
That plant has been producing cartridges since the early 1900s.
A second major plant operates in Oxford, Mississippi.
In 2025, Winchester completed acquisition of a newly built 185,000 square foot facility in Manitowoc, Wisconsin, picked up from AMMO Inc.
Winchester Ammunition also operates the government owned Lake City Army Ammunition Plant in Independence, Missouri, under a management contract with the US Army since October 2020.
Where Are Winchester Firearms Actually Built?
After the original Winchester Repeating Arms Company filed for bankruptcy, Belgian firm FN Herstal acquired the rights and assets in 1989.
The Winchester firearms name is now used under license by FN Herstal in Belgium and by Browning Arms Company, which manufactures out of Ogden, Utah.
So some Winchester firearms are built domestically, and others come from Belgium.
Is Winchester Ammunition Really Made in the USA?
For ammunition, the made in USA claim holds up well under scrutiny.
East Alton, Oxford, Manitowoc, and the government run Lake City plant are all domestic.
Per Wikipedia’s history of the Western Cartridge Company, which became part of Olin, the manufacturing footprint traces back over a century of continuous domestic production in the same Illinois region.
Winchester vs Remington: Who Makes Each?
Remington’s ammunition and firearms businesses were split up and sold off after its 2020 bankruptcy.
Vista Outdoor acquired the ammunition brand in that breakup.
That fragmentation mirrors what happened to Winchester decades earlier, when its own ammunition and firearms lineages split apart after a bankruptcy of its own.
What Is Next for Winchester?
Winchester Ammunition continues expanding its domestic footprint, most recently with the 2025 Manitowoc, Wisconsin acquisition.
The Lake City Army Ammunition Plant contract with the US Army remains active, keeping Olin’s Winchester division tied closely to government production needs.
On the firearms side, the licensing arrangement between FN Herstal and Browning Arms Company continues to split production between Belgium and Utah, with no signs of that structure changing.

Frequently Asked Questions About Where Winchester Is Made
Is Winchester ammo made in the USA?
Yes. Winchester Ammunition manufactures the large majority of its cartridges and shotshells at domestic facilities in Illinois, Mississippi, and Wisconsin.
It also operates the government owned Lake City plant.
Together these give Winchester Ammunition a genuinely strong claim to domestic production.
Are Winchester guns made in Belgium?
Some are. Winchester firearms are made in Belgium by FN Herstal, part of the licensing arrangement that followed the original company’s bankruptcy.
Others are built domestically by Browning Arms Company in Ogden, Utah.
So the country of origin depends on the specific firearm model, not the brand as a whole.
Are Winchester Ammunition and Winchester firearms the same company?
No. Winchester Ammunition and Winchester firearms have been separate companies with separate owners since the 1980s bankruptcy that split the original Winchester Repeating Arms Company.
Winchester Ammunition is owned by Olin Corporation. Winchester firearms rights belong to the FN Browning Group.
Who owns Winchester today?
Olin Corporation owns Winchester Ammunition, making cartridges and shotshells at plants across Illinois, Mississippi, and Wisconsin.
The FN Browning Group owns the rights to Winchester branded firearms, split between Belgian and Utah production.
Both companies use the Winchester name, but neither owns the other.
