I took my AMT Automag II in for service on extracting and feeding issues. 6 weeks later, right when they said, it was finished. And it runs better than when it was new!.Thanks Eli !

Great place to do business. Matt's crew are very knowledgeable and get right to the point when they are helping you. I have purchased multiple items from their Hubertus store over the past year and would highly recommend them to anyone looking for firearms maintenance, parts, pointers, or simple FFL needs.

First time visiting, came in with a cycle issue on a rifle. From the interaction on the phone, to chatting in the store with multiple employees, to one of their gunsmiths quickly fixing my issue... my experience was great. Will be back again and would definitely recommend to others.

Not a bad place for reloading supplies. Good prices and employee's friendly and helpful. I do not give any place 5 star because there is always room for improvement.

I had them assemble a custom .308 bolt gun. I purchased the parts and took them to their shop for the gunsmithing. Eli did a great job chambering and threading the barrel. He also glass bedded the action. All in all, MJ's did a great job. One area of constructive criticism... my stainless barrel was pretty scratched up. I buffed them out with a little bit of time. Also, the extractor on my bolt was not ejecting cases. I ordered a new one from Defiance and installed it myself, but I feel that's something that should have been checked. With a little more attention to detail, I think they could take their already great business up another notch. I will be returning to them for all gunsmithing needs moving forward.
