Gunsmithing is the art of designing, customizing, repairing, and making firearms. If you’re interested in guns and how they work, learning the basics of gunsmithing is a great skill to have.

Tips for Getting the Most Out of Your Online Gunsmithing Education

When taking free online gunsmithing courses, there are a few tips to keep in mind to get the most out of your education.

1. Do Your Research

Check reviews and ratings of the courses you’re interested in. See what other students say about the quality of lessons, helpfulness of the instructors, and overall experience. Look for courses with high student satisfaction and a proven track record of success.

2. Take Notes

As with any online class, take good notes as you go through the video lessons and readings. Write down key terms, facts, and processes so you have them for reference later on. Some courses may have downloadable lesson guides and workbooks to help with this.

3. Ask Questions

Don’t be afraid to ask your instructor questions about topics you don’t fully understand. They want you to succeed and are there to help clarify any confusing points. Ask follow up questions right away rather than struggling through subsequent lessons.

4. Practice and Apply

The best way to learn gunsmithing skills is through hands-on practice. Some courses may require you to acquire certain tools, equipment, and gun parts to work with as you follow along with the lessons. If possible, apply what you’re learning to your own firearm maintenance and repair projects.

5. Consider Earning a Certificate

Once you’ve completed a series of courses, you may be eligible to earn a certificate of completion or specialization. This can demonstrate your new skills and knowledge to potential employers or clients. Some schools offer gunsmithing certifications that require both online and in-person training.

Next Steps After Taking Free Gunsmithing Courses Online

The best way to gain real-world experience is through internships, apprenticeships, or entry-level jobs at a gun shop or sporting goods store. Even if it’s just a few hours a week helping out, you’ll learn valuable skills that you can’t get from online courses alone. You’ll become familiar with the daily operations, tools, and equipment used by professional gunsmiths. Over time, you can take on more responsibility and work your way up.

For example, to become a certified armorer for certain firearm brands like Glock or Sig Sauer, you need to complete their armorer certification programs. Check with gunsmithing schools in your area to see if they offer certification courses. Some online course providers also offer virtual certification courses.

3. Consider starting your own business

If you want to work for yourself, look into the requirements to start a licensed gunsmithing business in your city or state.

Build a business plan to outline your mission, target customers, marketing plan, and financial projections.

4. Keep learning

Technology, tools, and firearms are constantly evolving. Stay up-to-date with the latest innovations through industry publications, online courses, video tutorials, and hands-on practice.
