Is The One Horse the New Anderson Manufacturing?

One Horse Firearms bursts onto the scene in 2026 as the exciting new force in American-made AR-15s. This veteran-founded brand brings fresh energy and uncompromised reliability to shooters who demand gear that performs when it matters.

Launched officially on September 30, 2025, but hitting full stride this year, One Horse is already turning heads with its commitment to 100 percent domestic production, no shortcuts, and rifles built to work as hard as you do. In a market full of imported parts and inconsistent quality, One Horse stands out as a bold, homegrown alternative. It delivers rugged, dependable performance ready for anything.

Founded by U.S. Army veteran Jeremy Hammons, who brings over a decade of deep firearms industry experience including hands-on roles in assembly, engineering, machining, and rising to senior leadership, One Horse was born from frustration with corner-cutting and foreign dependencies. After witnessing too many companies prioritize cost over craftsmanship, Hammons set out to deliver truly trustworthy tools rooted in military values: integrity, precision, discipline, and zero excuses.

The result is a brand that feels genuinely new and purposeful for 2026, emphasizing American self-reliance and putting hardworking Americans first. Every rifle and component is built in the United States by skilled professionals using vetted materials and precise machining processes designed to ensure long-term reliability in real-world conditions.

Who Founded One Horse Firearms?

Jeremy Hammons, a U.S. Army veteran with real-world expertise spanning assembly floors to executive sales and marketing roles, leads the charge. His insider perspective on industry challenges fueled the creation of One Horse, ensuring every product meets his personal standard for dependability.

After more than a decade working inside the firearms industry, Hammons saw firsthand how many companies relied on imported parts and mass-produced builds that sacrificed consistency for cost savings. Determined to build something better, he founded One Horse with a simple goal: create rifles that hardworking Americans can rely on every day. His experience in engineering, machining, and firearms manufacturing helps guide the company’s approach to quality control and product design.

There is no hype, just performance you can count on.

Where Is One Horse Based and When Did It Launch?

Headquartered in Brownstown, Indiana, One Horse operates from a historic facility with deep manufacturing roots. The company revives American production in a place built for hard work and mechanical craftsmanship, reinforcing its focus on domestic manufacturing and skilled labor.

One Horse officially launched on September 30, 2025, with broader rollout and momentum carrying into 2026. The brand entered the market with a lineup of rifles and rifle components built entirely in the United States using carefully sourced materials and precision machining. As awareness grows and more dealers begin carrying the brand, 2026 is shaping up to be the year One Horse gains significant traction among shooters looking for dependable American-made equipment.

What Drives the Mission and Motto?

The mission is simple yet powerful: build complete rifles and parts with integrity, precision, and respect for the everyday Americans who rely on them.

The motto sums it up: “No shortcuts. No excuses. Just American-made reliability you can count on.”

At its core, the company focuses on restoring trust in American firearms manufacturing. Every product is built with the philosophy that a rifle should be as dependable as the person carrying it. That means precise machining, careful assembly, and consistent quality control from start to finish. By prioritizing domestic production and craftsmanship, One Horse aims to support American workers while delivering tools shooters can trust whether they are on the range, on duty, or in the field.

Are One Horse Products 100 Percent Made in the USA?

Yes. Everything is designed, machined, assembled, and tested entirely in the USA using high-grade domestic materials. Full control over the manufacturing process allows the company to maintain strict quality standards and ensure consistency across every rifle and component produced.

By sourcing materials from trusted American suppliers and performing machining and assembly domestically, One Horse keeps its supply chain close to home. This approach supports American manufacturing jobs while also ensuring that each part meets the performance expectations shooters demand. The result is a product line that reflects traditional American craftsmanship paired with modern machining precision.

Buying One Horse directly supports American jobs: machines run, tradesmen get paid, families get fed, and supply chains stay strong.

How Does One Horse Ensure Quality and Reliability?

Rigorous, hands-on quality control defines the brand. Each rifle is built with close attention to machining tolerances and component fitment before moving through final assembly and inspection.

Seasoned American gunsmiths oversee the process from raw material to finished rifle, ensuring that every component meets the company’s standards for precision and durability. After assembly, rifles undergo careful inspection, gauging, and live-fire testing to confirm reliable operation under real conditions. Only rifles that pass the full performance checklist are cleared for shipment.

This process helps guarantee that each firearm leaving the facility performs consistently and meets the reliability standards that the company was built around.

Are One Horse Rifles Compatible with Standard AR-15 Parts?

Yes. One Horse builds its rifles and components to industry-standard mil-spec specifications, ensuring compatibility with widely available AR-15 parts and accessories.

This means shooters can confidently integrate One Horse components into existing builds or upgrade rifles with aftermarket parts when needed. While the company designs its components to work seamlessly together, the use of standard specifications gives builders flexibility when customizing their setups.

For many enthusiasts, this compatibility makes One Horse parts an easy addition to new builds or performance upgrades without requiring proprietary components or specialized modifications.

What Calibers and Products Does One Horse Offer?

The focus is on versatile favorites like 5.56 NATO and .223 Remington for general-purpose shooting and training, along with .300 Blackout support in select components designed for shooters who want additional flexibility.

The lineup includes complete rifles, stripped receivers, complete lowers, bolt carrier groups, buffer tubes, and upper assemblies designed to serve as the foundation for custom AR builds. Rather than flooding the market with dozens of variations, the company concentrates on practical components that prioritize reliability, compatibility, and performance.

Each part is designed to integrate smoothly into the AR platform while maintaining the durability and precision that the brand emphasizes throughout its manufacturing process.

What Ammunition Works Best in One Horse Rifles?

For 5.56 NATO models like the OH-15 series, standard 5.56 NATO or .223 Remington ammunition from trusted manufacturers delivers reliable results. These cartridges are widely available and provide excellent performance across a variety of applications including training, recreational shooting, and defensive use.

Brass-cased ammunition from reputable brands generally offers the most consistent cycling and longevity in AR-pattern rifles. The platform’s chamber design allows it to handle both .223 Remington and 5.56 NATO loads safely when used within recommended pressure limits.

As with any firearm, shooters should follow safe ammunition guidelines and select quality loads that match the rifle’s specifications to maintain reliable performance.
