The RATL-R Vector FRS 9mm is a forced reset sear system engineered for the KRISS Vector 9mm platform, designed as a direct OEM fire control group replacement for Gen 2 and Gen 3 models. Built from 4130 steel, it delivers improved durability, faster trigger reset, and more consistent shot-to-shot control without permanent modifications to the firearm.
Operating as a mechanical forced reset sear system, the RATL-R uses bolt interaction during the firing cycle to assist trigger reset, reducing reset distance and enabling quicker follow-up shots while maintaining the standard semi-automatic firing function. It integrates directly into the existing Vector fire control architecture for a targeted performance upgrade.
Designed specifically for 9mm KRISS Vector rifles, the RATL-R includes a matching 3-position selector switch and installs as a non-destructive upgrade that can be reversed at any time. It is ideal for builders and shooters seeking a platform-specific forced reset trigger solution focused on consistency, control, and long-term reliability.

The RATL-R Vector FRS 9mm is a forced reset trigger system engineered specifically for the KRISS Vector 9mm platform. Designed as a direct OEM part replacement within the Vector’s fire control group, it delivers faster trigger reset, improved shot-to-shot control, and consistent performance, without requiring permanent modifications. Built from 4130 steel, the RATL-R is compatible with Vector Gen 2 and Vector Gen 3 configurations out of the box.
The RATL-R Vector FRS 9mm is a forced reset sear component that replaces the OEM sear in the KRISS Vector fire control group to provide mechanically assisted trigger reset, enabling faster, more consistent follow-up shots in the semi-automatic firing cycle.
Unlike a full KRISS Vector FCG upgrade, the RATL-R is a targeted component swap, not a complete trigger group replacement. It integrates directly into the existing Vector trigger reset system, adding a mechanical reset assist that activates during bolt interaction without altering the fundamental semi-automatic operation of the rifle.
The system is purpose-built for the 9mm Vector trigger upgrade market and is not designed for any other caliber or platform variant.
The RATL-R is machined from 4130 steel, a chromoly alloy selected for its balance of tensile strength and wear resistance. In a high-cycle application like a trigger reset component, this material provides the hardness needed to maintain dimensional accuracy over extended use without the brittleness associated with harder tool steels.
The 4130 grade is a common choice in precision firearm components where trigger durability and long-term performance under repeated mechanical stress are required.
The steel specification of the RATL-R is intentionally calibrated to be hard enough for durability, but soft enough to prevent accelerated wear on the surrounding Vector fire control group components. A component that is harder than the parts it contacts will cause those parts to wear faster, the RATL-R is engineered to avoid this.
The result is a trigger upgrade that extends service life on the Vector platform rather than accelerating wear on the FCG over high round counts.
Each RATL-R kit includes:
Both components must be installed together. The 3-position selector switch is required for the RATL-R trigger reset system to function correctly. The OEM selector is not compatible with the installed RATL-R.
Forced Reset Systems, including the RATL-R Vector FRS 9mm, use the Vector’s internal bolt interaction to assist trigger reset during the firing cycle. As the bolt travels through its rearward and return stroke, it contacts the RATL-R Vector FRS 9mm component and mechanically drives the trigger forward, completing the reset before the shooter would achieve it through a standard trigger release.
This compressed reset window is what defines Forced Reset Systems behavior: the shooter maintains trigger contact while the system handles reset, producing a shorter reset distance and faster readiness for the next shot.
The semi-automatic firing cycle, one shot per trigger pull, is maintained throughout. The Vector FRS trigger system does not alter the fundamental operation of the firearm.
The RATL-R delivers measurable improvements in the following areas:
The RATL-R is a drop-in replacement component for Gen 2 and Gen 3 KRISS Vector rifles. Both generations share the fire control group architecture that the RATL-R is designed around. No receiver modification, no additional parts, and no gunsmithing beyond the installation itself is required for these builds.
This is the primary intended configuration and the one with the most predictable installation and performance outcome.
The RATL-R is not compatible with the Gen 1 KRISS Vector FCG. The Gen 1 fire control group uses a different internal architecture that does not accept the RATL-R component.
Note: Gen 1 Vector owners who want to use the RATL-R must first upgrade the rifle’s fire control group to Gen 2/3 spec. KRISS USA offers an FCG upgrade service, contact KRISS directly for availability and pricing before purchasing the RATL-R.
The RATL-R Vector FRS 9mm is engineered exclusively for the 9mm KRISS Vector platform. It is not designed, tested, or warranted for use on any other KRISS caliber variant, carbine, or firearm platform. Do not attempt installation in non-9mm Vector configurations.
The RATL-R replaces a single OEM component in the Vector fire control group. No permanent modifications are required, it is a non-destructive upgrade that can be reversed by reinstalling the original OEM part.
Installation involves disassembly of the Vector FCG and correct seating of both the RATL-R trigger component and the included 3-position selector switch. The process requires moderate familiarity with the Vector’s internal components.
Professional installation by a qualified gunsmith is strongly recommended. Incorrect installation of the RATL-R can result in unsafe function. If you are not experienced with KRISS Vector FCG work, seek gunsmith services before proceeding. See the gunsmith installation service listing for assistance options.
For KRISS Vector owners evaluating a Vector fire control group upgrade, the RATL-R provides focused performance improvement without the complexity of a full FCG replacement or permanent platform modification.
As a rapid reset trigger Vector upgrade, the RATL-R delivers a technically specific improvement to the Vector’s trigger timing and control without altering the core operating system of the rifle.
The RATL-R is fully compatible with Gen 2 and Gen 3 KRISS Vector rifles chambered in 9mm. It is not compatible with Gen 1 Vectors without a prior FCG upgrade, and it is not designed for any non-9mm Vector variant. Confirm your generation and caliber before purchasing.
No, the RATL-R is not directly compatible with the Gen 1 KRISS Vector fire control group. Gen 1 owners must first upgrade the FCG to Gen 2/3 architecture through KRISS USA’s upgrade service. Contact KRISS USA directly to inquire about FCG upgrade availability before ordering the RATL-R.
No permanent modifications are required. The RATL-R replaces a single OEM component in the fire control group and can be reversed by reinstalling the original OEM part. No drilling, machining, or receiver alteration is involved.
The kit includes two components: the RATL-R trigger component (the forced reset mechanism itself) and a 3-position selector switch that replaces the OEM Vector selector. Both components must be installed together. An included selector switch is required for the RATL-R system to function correctly.
Professional installation is strongly recommended. While the RATL-R is a single OEM component replacement, it requires the correct installation of both the trigger component and selector switch within the Vector FCG. Incorrect installation can result in unsafe function. If you are not experienced with KRISS Vector FCG work, use the available gunsmith installation service.
