Why this build is an SBR — and what that means

This configuration is a Short-Barreled Rifle under the National Firearms Act: a rifle with a barrel under 16 inches. Owning one requires ATF registration and a background check. As of January 1, 2026, the federal tax for SBRs, SBSs, AOWs, and suppressors is $0 — but registration is still required; only the tax was eliminated. The suppressor on this build is its own NFA item with its own registration.
