"Grandfathered" gets thrown around a lot in conversations about this law, often doing more work than it can actually support. Here's a precise breakdown of what it does and doesn't cover.
What's protected
Both the Department of Revenue and Colorado Parks and Wildlife have stated this plainly: if you legally own an SSF-pattern firearm before August 1, 2026, you are not required to surrender it, register it, or modify it. The restriction in 18-12-116(2) reaches manufacture, distribution, transfer, sale, and purchase of an SSF on or after August 1, 2026 — it does not reach simple possession of something you already own. If you bought your AR-15 last year, or last week, before that date, nothing about owning it changes.
What "grandfathered" does not mean
It does not mean you can freely sell, gift, or otherwise transfer that same firearm to another Colorado resident after August 1 without restriction. A transfer is still a transfer under 18-12-116(2), regardless of when you originally acquired the gun. After the effective date, transferring an SSF to another Colorado resident is restricted to the same channels as any other post-August-1 transfer: the recipient holds a valid eligibility card and has completed the required safety course, the recipient is an FFL dealer, the recipient lives in another state, or the transfer falls under one of the narrower carve-outs (estate/trust transfer by operation of law, law enforcement, and so on). Owning your rifle is grandfathered; who you can hand it to later is not.
A question we see a lot: moving to Colorado with an SSF you already own
The statute restricts manufacture, distribution, transfer, sale, and purchase — not possession, and not the act of moving into the state with a firearm you already legally own. On its face, SB25-003 doesn't appear to address new-resident moves at all. That said, this bill isn't the only law that could theoretically touch a firearm coming into Colorado, and "the statute doesn't mention it" isn't the same as "there's definitely no issue" — if this applies to you, it's worth confirming independently rather than assuming based on this one law.
The short version
Grandfathering protects what you already have. It doesn't extend automatically to what you do with it next.
