About FrameForge

FrameForge was founded to serve the precision‑focused builder who demands polymer pistol frames and 80% lower receivers that meet exacting tolerances. Every component in our catalog is vetted through a series‑of‑stress‑analysis cycles and dimensional audits before it reaches the shelf.

Our lead engineer, Liam K. Ortego, brings fifteen years of hands‑on experience from OEM production lines to custom‑shop benches. He began as a CNC programmer at Nova Arms, where he honed tolerance‑critical machining processes for polymer frames and aluminum lowers. Liam’s background in mechanical engineering and his published work in American Firearms Quarterly shape every specification you see on our site.

We select raw polymers based on impact resistance, heat‑deflection temperature, and long‑term dimensional stability. Each batch is heat‑treated in a controlled oven cycle, then measured on a CMM to ±0.005 mm. The result is a frame that resists warpage, maintains a consistent trigger pull, and integrates cleanly with a wide range of 80% lowers.

Our inventory is curated, not exhaustive. We carry only the profiles that have passed our in‑house endurance testing, and we provide full machining drawings so you can verify fit on your own workbench. If a geometry isn’t on our site, we’ll source or custom‑machinate it within a three‑day quoting window.

FrameForge respects the builder’s expertise. We supply the data, the tolerances, and the support you need to finish a firearm that performs exactly as designed.
