Educating. Activating. Empowering Americans.
The Second Amendment Institute is a 501(c)(3) nonprofit organization founded in June 2016 by Tyler Yzaguirre. SAI exists to equip Americans with the facts, legal insight, and civic tools needed to effectively defend the constitutional right to keep and bear arms.
Principled Education
Education is the cornerstone of SAI’s work. Through fact-based advocacy and sound legal analysis, the Institute confronts attacks on the Second Amendment while countering misinformation with clarity, credibility, and conviction.
Changing Hearts and Minds
By advancing verifiable facts over political rhetoric, SAI works to persuade Americans across ideological lines—including those who have traditionally supported restrictive gun-control policies.
Training the Next Generation
SAI is recruiting and preparing a new generation of Second Amendment advocates, including Americans committed to strong self-defense protections on college campuses and beyond.
SAI in Action
Through strategic digital outreach, direct mail, national events, and grassroots engagement, SAI operates where education, advocacy, and public mobilization intersect.
A Durable Defense of Freedom
The Second Amendment Institute stands on the front lines of public education and constitutional advocacy. As a non-political organization focused on long-term impact, SAI works to unite Americans around a shared constitutional principle: that the right to keep and bear arms must remain protected not only in law, but in public understanding. With your support, SAI will continue building a lasting defense of freedom for generations to come.
