Kriss Vector Mamba

The MAMBA Trigger was built for KRISS Vector owners who want a trigger that’s ready to go when they are.

The MAMBA Trigger takes its name from one of the most aggressive and formidable snakes in the world, The Mamba. Known for speed, decisiveness, and relentless follow-through, the mamba doesn’t hesitate once it commits. 

If the RATL-R is quick and precise, the MAMBA Trigger is its more aggressive, purpose-driven counterpart, built for shooters who want a heavier assist and faster reset feel on the KRISS Vector platform.

Think of the MAMBA Trigger as the bigger, meaner cousin in the family. Sharing the same DNA, but tuned for a more assertive performance profile.

Heavily assisting trigger reset during the firearm’s normal cycling operation, MAMBA Trigger, helps reduce the dead time between shots, so follow-ups feel quicker, smoother, and more predictable.

Unlike the RATL-R, which utilizes a multi-position selector, the MAMBA Trigger operates using a simplified two-position setup:

When placed in the MAMBA position, the system functions the same way as the RATL-R’s assisted-reset position, providing substantial assistance to trigger reset during the firearm’s normal cycling operation.

There are no additional firing modes and no changes to how shots are initiated. The difference is simplicity: SAFE or MAMBA.

If you’re familiar with the RATL-R, the MAMBA position is essentially the RATL-R position, just without the extra selector options.

Intended for installation by a knowledgeable individual or qualified gunsmith.

Important Notes & Disclaimer

The MAMBA Trigger, assists trigger reset, it doesn’t guarantee reset speed under all conditions and doesn’t function independently of the shooter.
Like any mechanical component, performance depends on the system it’s installed in and how it’s used.
Always follow all firearm safety rules and confirm compliance with all applicable local, state, and federal laws before installation or use.

As the Vector cycles, the MAMBA Trigger interacts to assist the trigger’s return toward its reset position. That assistance shortens the reset phase and gets the trigger ready for the next pull more quickly, while still requiring deliberate input from the shooter for every shot.

Nothing fires on its own. Nothing overrides safeties. You’re always in control.
