About Us


Fine Line Firearms LLC is a Massachusetss gun store offering high quality firearms, ammunition, gunsmithing services, estate sale services, and comprehensive pre & post sale support!

Established in 2012, we have been providing the Middlesex county area and beyond with high quality arms and accessories, in an alternative gun store atmosphere. Are you new to firearms ownership and want something you can depend on? In the market for a customized firearm to meet all your needs? How about a new upper for your gun? Does your training facility or department need a post-dealer sample or dummy firearm? Self Defense Enthusiasts, Collectors, Hunters, or Competitors will find what they need at Fine Line Firearms LLC.

We are not your typical MA gun store. If you enjoy the assembly line buying experience, we likely won’t be for you. We offer personal one on one service and attention to detail. An appointment with us guarantees our full and undivided attention, with no lines, no waiting, and no grumpy gun guys. New shooters are always welcome!


Gov. Healey has added an Emergency Preamble to the H.4885 Gun Bill. This bill will greatly impact the way Firearm Dealers and Citizens in the state of Massachusetts will operate. Check out our post here.
