About Polymer 80 USA

About Polymer 80 USA

Polymer 80 USA is an independent US reseller of Polymer80 80% pistol frames, AR-15 and LR-308 80% lowers, jig kits, slide assemblies and the small parts that finish a build. We are not the manufacturer and we do not sell complete firearms or conversion devices.

What we do differently is fitment. Every product page names the exact Gen 3 slides, magazines and parts kits a frame accepts, and if you email us the slide model you own we confirm the frame before you pay. Orders ship tracked from a US warehouse in one to two business days.
