John Andrewski Gunsmith

John Andrewski Gunsmith operates independently from a shop in Manchester, NH, drawing on two decades of hands-on experience in the firearms industry. The business started as a family operation—Andrewski worked alongside his father Stan at Stan's Gun Shop in Webster, NH—and has since built a national reputation for specialized work.

Nationally known for extensive knowledge and ability to repair, reactivate, and service a wide variety of NFA weapons, with concentration in pre-1950s machine guns.

While Andrewski handles both Title I (standard firearms) and Title II (NFA) weapons, his specialty is NFA work. He's recognized across the industry for his expertise with Thompson submachine guns, M1918 BARs, and other Class 3 weapons. Though much of his work comes from manufacturers and dealers, he welcomes direct client projects and maintains an extensive network of parts vendors.
