Colorado NFA Gun Trusts
While you can purchase NFA items as an individual, many Colorado residents choose to use an NFA gun trust for added benefits:
Shared Possession
Multiple trustees can legally possess and use NFA items without the owner present.
Simplified Inheritance
NFA items pass to beneficiaries outside of probate, avoiding complex transfer processes.
Privacy
Trusts are not public record in Colorado, keeping your NFA ownership private.
Flexibility
Add or remove trustees at any time as your situation changes.
Do you still need a trust after the tax change? Yes! The $0 tax stamp only eliminated the fee—all other benefits of trusts remain intact.
