Marble Duck

---

I'm Muir, an active duty U.S. Army officer and owner of the Marble Duck Small Arms Research Center, a shop currently located outside of Fort Huachuca, AZ. Over the course of my work with partner forces across Eastern Europe and the post-Soviet sphere, including Ukraine, Kyrgyzstan and Poland, I've since developed an appreciation for the quirks of Cold War weaponry.

I bring developments in CAD, 3D printing and 3D scanning to deliver the best product to the buyer, whether you're looking for a competition AK or a classic or modernized HK build.
