Work in a large clean space: Creating the right space will help keep you organized, focused, and in the right state of mind.

The room itself should be quite and free of distractions and home foot traffic.

Stay organized: Work methodically and take notes of what you are doing. Remember a missing part can be an expensive and time consuming mistake. Have several containers to keep all your gun parts organized. Line up the containers in the order of disassembly. This way if you get stuck you can always retrace your steps by having your parts in the right order.

Use proper tools and equipment: Guns are finely craft with precision. Using the wrong sized screwdriver or a cheap punch can quickly damage your prized firearm. If you are just starting out there are several good kits that will provide you all the basic tools. Over time you’ll need to replace and upgrade certain tools.

Use precision over power: If a piece or a part is not working it is usually due to misalignment vs. lack of power. Work slowly. Check for alignment and fit. If you become frustrated don’t be afraid to take a break. A break will often give you a fresh perspective and the piece will quickly fall into alignment.

If you are doing a lot of home gunsmithing projects, you can also consider buying a gunsmith quality torque driver. A torque driver allows you to carefully control the torque so you avoid stripping screws.

If you get stuck. Go to a pro: If you have read the manual, checked online for a solution, and even taken several breaks and still are having issues with your home gunsmithing project, go to a pro. Guessing at the next step and trouble shooting can lead to expensive and sometime dangerous results. If you have taken good notes and stayed organized then it should be very easy for a licensed gunsmith to pick up your project.
