The RATL-R Vector FRS (Rapid Assist Tactical Load-Reset Trigger) is a precision-engineered forced reset trigger system designed for KRISS Vector platforms chambered in 40 S&W, 45 ACP, and 10mm. Built from 4130 steel, it replaces a single OEM fire control group component to deliver faster trigger reset, improved shot-to-shot consistency, and enhanced shooting performance without permanent firearm modifications or electronics.
Operating as a mechanical load-reset system, the RATL-R uses internal bolt interaction to assist trigger reset during the firing cycle, reducing reset distance and creating a more consistent, repeatable trigger response. This targeted design improves follow-up shot speed while maintaining the platform’s standard semi-automatic operation.
Compatible with GEN2 and GEN3 KRISS Vector models, the RATL-R installs as a non-destructive upgrade and includes a required 3-position selector switch for proper function. Designed exclusively for the Vector platform, it offers a durable, mechanical solution for shooters seeking a refined trigger reset system built for reliability and performance.

The RATL-R Vector FRS, short for Rapid Assist Tactical Load-Reset Trigger, is a precision-engineered forced reset trigger system designed for KRISS Vector platforms chambered in 40 S&W, 45 ACP, and 10mm. Built from 4130 steel and requiring no permanent modifications to the firearm, it replaces a single OEM component in the KRISS Vector fire control group to deliver faster trigger reset, improved shot-to-shot consistency, and enhanced tactical shooting performance, all without electronics.
The RATL-R Vector FRS (Rapid Assist Tactical Load-Reset Trigger) is a mechanical forced reset sear system that replaces the OEM sear in the KRISS Vector fire control group to provide faster, mechanically assisted trigger reset with no permanent modification to the firearm.
Unlike a full Vector FCG upgrade, the RATL-R is a targeted, drop-in sear system that works within the existing Vector architecture. Its load-reset mechanism uses internal bolt interaction to drive the trigger forward during the firing cycle, compressing reset distance and improving follow-up shot speed.
This Vector trigger enhancement is engineered specifically for the 40 S&W, 45 ACP, and 10mm KRISS Vector platform, not adapted from another system.
The RATL-R is machined from 4130 steel, a chromoly alloy that balances tensile strength with controlled hardness. In a high-cycle trigger component, material choice is critical: too hard and the part accelerates wear on surrounding FCG components; too soft and it degrades under sustained cycling.
The 4130 specification positions the RATL-R to provide long-term fire control durability while protecting Vector internals from accelerated wear. This is particularly important in a non-permanent modification, the firearm should be in equal or better condition when the OEM component is reinstalled.
The load-reset mechanism inside the RATL-R Vector FRS 9mm works by harnessing internal bolt movement to push the trigger forward during the firing cycle. This produces a shorter, more consistent reset point that is defined by mechanical geometry, not by the shooter’s release distance.
The result is measurably improved trigger reset performance: faster readiness between shots, more consistent reset feel, and better fire control confidence during rapid engagement. The system is entirely mechanical, no batteries, no electronics, no additional failure points.
The RATL-R Vector FRS is a fully compatible drop-in trigger system for KRISS Vector GEN2 GEN3 models in 40 S&W, 45 ACP, and 10mm. Both generations use the same fire control group architecture that the RATL-R is designed around. Installation requires no receiver modification, no additional parts, and no alteration to the firearm’s original configuration.
This is the primary supported platform and the configuration with the most predictable installation and performance outcome.
The RATL-R is not directly compatible with the GEN1 KRISS Vector FCG upgrade architecture. The GEN1 fire control group uses a different internal geometry that does not accept the RATL-R component without prior modification.
Note: GEN1 Vector owners must first upgrade the fire control group to GEN2/GEN3 specification before installing the RATL-R. Do not attempt to install the RATL-R in a GEN1 Vector without completing the FCG upgrade first.
KRISS USA offers an official FCG upgrade service that converts GEN1 Vector rifles to GEN2-level fire control group specifications. This service brings the GEN1 platform into full RATL-R compatibility while also improving overall Vector trigger enhancement and reliability.
GEN1 owners: purchase the FCG upgrade directly from the KRISS website before ordering the RATL-R Vector FRS. See the KRISS Vector upgrade service page for current availability and service pricing.
Each RATL-R kit includes two components that must be installed together:
The included 3-position selector provides the same selector safety positions as the OEM part while integrating correctly with the RATL-R’s reset geometry. The OEM selector is not compatible with the installed RATL-R and must be replaced with the included unit.
Both the RATL-R trigger and the 3-position selector must be installed together. Installing the RATL-R without replacing the OEM selector will result in incorrect function. Do not mix components.
While the RATL-R replaces only a single OEM selector replacement and trigger component, correct fitting within the KRISS Vector FCG requires precision alignment and a thorough function check. Incorrect installation can result in unsafe trigger behavior.
Installation is not recommended for users unfamiliar with KRISS Vector fire control group disassembly and reassembly. A qualified gunsmith with Vector FCG experience should perform or supervise the installation.

For KRISS Vector owners evaluating a Vector trigger upgrade in 40 S&W, 45 ACP, or 10mm, the RATL-R delivers targeted, engineering-grounded performance improvement without altering the fundamental character of the platform.
No. This version of the RATL-R Vector FRS is designed specifically for KRISS Vector models chambered in 40 S&W, 45 ACP, and 10mm. A separate RATL-R variant is available for the 9mm Vector platform. Do not install this version in a 9mm Vector or any other caliber variant.
The GEN1 KRISS Vector fire control group uses a different internal geometry than GEN2 and GEN3 models. The RATL-R component is dimensioned for the GEN2/GEN3 FCG architecture and cannot seat or function correctly in the GEN1 configuration. GEN1 owners must complete the KRISS FCG upgrade service before the RATL-R can be installed.
Yes. The 3-position selector switch included in the kit must be installed alongside the RATL-R trigger component. The OEM Vector selector is not compatible with the RATL-R’s reset geometry. Both components must be installed together for the system to function correctly and safely.
No, provided installation is performed correctly. The RATL-R is engineered from 4130 steel, specifically calibrated to be hard enough for durability without being hard enough to accelerate wear on the surrounding Vector FCG components. The upgrade is non-permanent. The OEM parts can be reinstalled without any lasting modification to the firearm.
Professional installation is strongly recommended. The RATL-R involves replacing FCG components and requires correct alignment and a thorough function check. Users without experience in KRISS Vector FCG work should contact Harrison Gunworks (harrisongunworks@gmail.com) for installation services before or after purchase.
