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.
About Us
Fine Line Firearms LLC is a Massachusetts FFL dealer and firearms manufacturer serving Middlesex County and surrounding areas since 2012. We offer firearms sales, ammunition, gunsmithing, estate services, and full pre and post sale support in a personalized, appointment based setting.
As a federally licensed Type 07 FFL manufacturer, we are authorized to build, assemble, and customize firearms in house. This allows us to provide custom firearm builds, AR 15 uppers, modifications, post dealer sample and dummy firearms, and specialized solutions for individuals, collectors, and professional users.
We are not a traditional Massachusetts gun store. We focus on one on one appointments, expert guidance, and detailed customer service with no lines, no waiting, and no rushed transactions. New shooters are always welcome.

We will buy your guns: estates or collections.
Fair prices, we pay cash!
