I am an experienced and knowledgeable gun owner. I have formal training and I am an avid gun enthusiast. I watch countless hours of videos on weapon and tactical philosophies, reviews, and performance. Ive read books and articles on them, learned how to do minor gunsmithing, and pretty much try to learn anything I can related to the field.Jason, the head gunsmith and engineer, at neponset valley gun smiths makes me seem like a noob. His expertise from real life experience in the areas of machining, engineering, design, tactical firearms handling, and weapon systems as a whole is unmatched. His professionalism and knowledge will blow you away from the second you ask your first question.There is nothing beyond his skill level and his understanding of your firearm. He will be able to do things better than you hoped and probably, even better than you knew it was possible to be done. From something as simple as sighting in a scope, cerakote, trigger work to fabricating a new barrel from a block of metal to designing something that hasnt been invented yet.. If someone can figure out a solution, its him.
