Whether you have a turn of the century gun or present day firearm, or somewhere in between, our gunsmith is an expert at performing some of the best gun repair services in the twin cities. From deep cleaning and repairs to simple or extensive modifications, we’ll make sure your gun is working at the highest level possible.

Our gunsmithing services provide you the confidence that all components of your gun are working together fluidly. Both weather and time can cause certain parts to expand or contract. A gun can collect dust even if in a case. A successful fire requires a few actions to take place in synch and small glitches between two moving parts can not only hinder your firing, but also prove to be dangerous. Our gunsmith will ensure a successful and safe fire.
