About Polymer-80

About Polymer-80

Polymer-80 was founded by craftsmen who understand that a reliable firearm starts with a precision frame. We're not distributors—we're builders who've handled thousands of Polymer80 frames and know exactly what makes them work. Our team consists of experienced gunsmiths and firearms enthusiasts who've spent years in the workshop, not just behind a counter.

Caleb J. Reisinger leads our technical operations, bringing 14 years of hands-on experience since his Army service as a small arms repair specialist. After his 2008 discharge, Caleb spent six years as senior frame specialist at Atlantic Gunsmithing, where he personally assembled or inspected over 2,500 P80 kits. This background informs every product we carry and every piece of advice we offer.

Our selection is specifically curated for builders who demand precision. We carry only frames and components that meet our strict tolerances—nothing gets listed that we wouldn't use in our own builds. Each product page includes detailed specifications and compatibility notes because we understand that half-millimeter differences matter when you're building for reliability.

What separates us from larger retailers is our focus on the build process itself. We don't just sell parts; we provide the technical support to ensure they work together correctly. Every kit we offer has been tested for compatibility and includes notes on common fitting issues and solutions.

We maintain a lean inventory of proven performers rather than chasing every new product on the market. If we stock it, we've verified the mold quality, polymer consistency, and jig precision. This approach means you get parts that work right out of the box, without the guesswork that plagues many first-time builders.
