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!

H.4885 changes the way gun stores operate as a business and what residents can buy in the Commonwealth. We spent quite a bit of time combining the new law into the existing published MA General Law, to actually comprehend it. Check out our post if you’d like to know more.

I am beyond impressed with Fine Line Firearms. Extremely knowledgeable and genuinely helpful for a newbie like myself. If you are looking for a variety of rifles, including custom, I would strongly recommend setting up an appointment and visiting. Hands down the best gun shop environment I have visited. A+++
