As an authorized distributor of ZOLLERN —an industry leader with over 300 years of metallurgical expertise—we deliver the highest quality materials to support mission-critical components in firearm production. 

Our products meet the exacting standards of firearm OEMs, defense contractors, and high-end custom gun manufacturers.

Our partnership with ZOLLERN brings centuries of innovation and metallurgy expertise to your production floor. The ZOLLERN Group, one of Germany’s oldest family-run industrial companies, develops and produces high-quality metal products across several global facilities. With a focus on precision and durability, Zollern profiles enable manufacturers to improve efficiency, reduce waste, and produce superior small arms components.

We stock a wide range of metal shapes to serve the evolving needs of the firearm industry. From AR-15 gas blocks to 1911 slides, our near-net shape steel profiles reduce material waste, machining time, and costs—while delivering the precision needed for modern CNC environments. We’re proud to serve applications including:

• Firearm OEMs
• Hunting and Sporting Arms
• Target Shooting
• Defense Contractors
• Law Enforcement Firearm Programs

Arbor Metals delivers consistent, high-quality profiles designed specifically for firearm manufacturing. Our inventory supports rapid fulfillment for small to medium-sized U.S. gun makers, with customizable options to meet tight production tolerances.

Products we supply include:

• Special profiles in alloy & stainless steel
• Round bars in stainless steel, aluminum, nickel alloys, and titanium.
• Square bars in stainless steel, aluminum, nickel alloys, and titanium.
• Rectangle bars in stainless steel, aluminum, nickel alloys, and titanium.

These materials help manufacturers produce vital metal components for firearms like bolt carriers, slide profiles, upper receivers, and fire control groups. With optimized shapes and tighter dimensional tolerances, our profiles work seamlessly with advanced machining centers.

Steel profiles for firearm manufacturing offer significant benefits over traditional billet or bar stock, especially for modern production lines:

• Reduced Machining Time – Fewer operations needed to reach final dimensions
• Increased Material Efficiency – Less scrap waste and more usable yield
• Lower Production Costs – Up to 40% cost savings compared to traditional manufacturing, per ZOLLERN data
• Tighter Tolerances – Ideal for high-performance, high-precision firearm parts

Whether you’re machining custom slides, bolt carriers, or gas blocks, steel profiles for gun manufacturers deliver measurable gains in throughput and product consistency.

In addition to steel profiles, Arbor Metals provides high-strength round bars and tubes to meet varied firearm manufacturing requirements. These shapes are ideal for producing small arms components like barrels, guide rods, and internal support parts. Our deep inventory and commitment to material traceability ensure consistent performance from prototype to production.
