Greylock Gunworks

Todd O'Neil opened Greylock Gunworks in 2024 after 30+ years in the trade. He trained at Trinidad State College in Colorado, worked alongside Ferlach and Birmingham gunmakers at Connecticut Shotgun Mfg., and spent 15 years as a gunsmith at Pete's Gun Shop in Adams while also serving as Berkshire County Sheriff's Department Armorer and Firearms Instructor. In 2024, he was accepted into the American Custom Gunmakers Guild—an honor that reflects his hand-carved rifle work and reputation among the country's best.
