No. Rapid-fire devices, including FRTs, are dangerous weapons; possession is a class 5 felony. Effective 2025-04-10.
Controlling law: Colo. Rev. Stat. §§ 18-12-101(1)(g.7) & 18-12-102 (SB25-003, 2025)
Contested entry
In force since signing on April 10, 2025 (the act carries a safety clause, so it took effect on approval). SB25-003 defines rapid-fire device broadly (any part or kit increasing a semiautomatic's rate of fire above standard) and adds it to the dangerous-weapons list. The separate August 1, 2026 date applies only to the specified-semiautomatic purchase-gating regime in § 18-12-116(2), not the device ban. No grandfather clause.
The statute in practice
Colorado SB 25-003 created a rapid-fire-device category and placed covered devices in the dangerous-weapons statutes. The definition reaches a part, device, attachment, or accessory designed or functioning to materially increase a semiautomatic firearm's rate of fire above its unmodified rate.
The act carries a safety clause and took effect when signed on April 10, 2025. That effective date is distinct from the later date attached to Colorado's specified-semiautomatic-firearm purchase requirements.

What it means for you
The device provisions address possession as well as commercial transfer, and the enacted text does not create a general grandfather clause. Read the rapid-fire-device definition and the dangerous-weapons offense together.
Federal law
Under the 2025 DOJ settlement with Rare Breed Triggers, an FRT fires one round per trigger function and is not an NFA machine gun federally. The settlement covers rifles and grip-forward pistols; it does not extend to grip-fed handguns (Glock, S&W M&P, Canik), whose federal FRT status remains less settled. State bans operate independently of federal law through broader state machine-gun, trigger-activator, or rate-of-fire definitions.
Scope: Forced reset triggers (Rare Breed FRT-15, Dairyland Defender, and similar) and forced-reset selectors (AR Super Safety, ARC-Fire). One round per trigger function. Binary triggers are a separate class.
