Stuff and Things CARL Cam Activated Reset Limiter with 3-Round Cam - C.A.R.L, 3-Round

Enhance your AR-15 platform with the Stuff and Things CARL Cam Activated Reset Limiter with 3-Round Cam, a precision-engineered accessory designed to work seamlessly with compatible super safety systems. This drop-in component introduces a controlled extension to trigger reset after every three rounds fired, providing shooters with a legal method to moderate firing cadence while maintaining full semi-automatic functionality.

Key Features

• 3-Round Cam Design: Limits trigger reset after three consecutive shots, requiring an extended release for the next cycle to promote deliberate shooting and target reacquisition.
• Drop-In Installation: No modifications required; installs directly into mil-spec trigger and hammer setups paired with compatible super safeties.
• Durable Construction: Crafted from 4130 steel and stainless components with a nitride finish for corrosion resistance and long-term reliability in demanding environments.
• Interchangeable Cam System: Supports optional 2-round or 6-round cams for customizable reset intervals without replacing the entire unit.

How It Works

When paired with a super safety, the CARL system uses a cam mechanism on the hammer and disconnector assembly. After the third round, the cam interfaces differently to slightly lengthen the trigger reset distance, forcing a more pronounced release before the next shot can be fired. Without a super safety installed, the trigger functions as a standard mil-spec semi-automatic unit.

Upgrade your trigger system today with this innovative limiter for a more disciplined and effective shooting experience. Federal law defines a “machinegun” as a weapon that shoots, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger (26 U.S.C. § 5845(b)).
The forced reset triggers sold by [Company] are semi-automatic triggers. They fire one round per single function of the trigger. After each shot, the trigger must mechanically reset and complete a separate function before the firearm will fire again. These devices do not convert a semi-automatic firearm into a machinegun.
Altering, modifying, or combining an FRT with other parts so that a firearm fires more than one round per single function of the trigger may create an unlawful machinegun under 18 U.S.C. § 922(o) and the National Firearms Act. [Company] is not responsible for any modification, misuse, or improper installation.
State and local laws vary, and some jurisdictions restrict or prohibit FRTs. We do not ship FRTs to WA, OR, CA, NV, CO, MN, IL, HI, FL, NY, MA, RI, CT, NJ, DE, MD, DC, and Territories By purchasing, you represent that you may lawfully possess this item where you reside and where it will be used. You are solely responsible for knowing and complying with all applicable federal, state, and local laws. [Company] reserves the right to cancel any order it believes may violate applicable law.
