Mark and the staff at Fineline Firearms couldn't have been more helpful to me. They were knowledgeable and friendly, answered my questions and had lots of good advice. I will be going back to Mark for any future gun purchases I need to make.

I had a good experience here. I submitted a request on their website and got an email back within an hour(AM on weekday). Verified that they had what I wanted and was able to schedule an appointment for pickup the same day. The shop was easy to get to from 495. Staff were knowledgeable, friendly and were able to answer the questions I had easily. I'll contact them first for my next big purchase.

Working with Fine Line Firearms was a fantastic experience. When I had questions about availability, they were able to get back to me immediately, and I could pick up the item I needed the following day. Excellent customer support and will be looking forward to future purchases.

This was my first experience with Mark and Fine Line Firearms. It was great. They had listed a somewhat unusual gun that I was interested in. I contacted them and confirmed the condition and price. I made a convenient and went in to purchase the gun. It was just as described, Everything and everyone was great and I would love doing business again with them.

Super friendly staff, took the time to chat with me, made sure I knew everything about the gun I purchased, and threw in a magazine and ammo in for free!

I went to fine line gun shop today & met Mark who was very friendly, informative, & knowledgeable, professional. he spent a lot of time explaining guns to me ( I am new to all this) but he took his time and explained so much to me about; guns, laws & safety. He was more than generous with the amount of time he spent with me! I feel so much better educated & informed because of the information he shared with me. Thank you Mark

Great buying experience. Super knowledgeable and took the time to field strip the gun to show me how to and all the parts. Great communication before and after the purchase. Had a small issue that was taken care of immediately. Would definitely recommend.

Mark is awesome. He has a great approach with his one on one appointments with no pressure and all the time you need. I will be recommending him to friends.

A great little appointment only shop with a nice selection of firearms. Lots of Pre-Bans. Helpful staff and competitive prices. You won't need to grab a deli ticket and stand around for an hour only to be rushed out! I honestly wish I knew about it years ago.

I'm new to gun ownership and my son and I happened upon Fine Line Firearms as it's a local gun 'parlor'. I'm so glad we did, we found Mark (Owner) to be super friendly, knowledgeable, and generous with his time. We were put immediately at ease and learned a lot. Ended up with a very nice set up, P365XL with a red dot and laser/light, set up and tutorial. Highly recommend.

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+++

Great business. I went to Fine Line because I wanted a Robinson Arms XCR, and Mark is the only FFL I could find in MA who is familiar with the gun. He knows a lot about the company and walked me thru the custom order process to get everything built exactly to spec. Was super responsive during the wait time, and did the compliance modifications as soon as it came in. Came out perfect!All around great shop and owner. I’d highly recommend Fine Line especially if you’re looking for something more specialized that you won’t find at your average store.
