"I've known several 'gunsmiths' but I find your craftsmanship and finish superb and qualify you for inclusion not only as an excellent smith but as a true 'martial artist'." — Tom F., Lawtons, NY

Testimonials consistently highlight the quality and attention to detail. One customer noted that John "turned a $300, 30-year-old gun into a $600 brand new gun" with meticulous Cerakote work on all small parts and details. Another notes: "I have 35 years of service between the US Military and Law Enforcement...I will only trust one person to work on any of my firearms. John Newberry is that man."

Beyond firearms work, John has DuraCoated prosthetics for wounded warriors and those injured in the Boston Marathon bombing—a reflection of the shop's commitment beyond business.
