Best KRISS Vector Forced Reset Triggers 2026

Buy by budget and selector layout, because build quality tracks price closely in this niche. The Duality Arms RATL-R ($250) is the pick if you want the most durable body and the most established name; its 4130 steel and included selector cam make it the reference. If you want three positions for under $100, the Continental Customs C.A.R.T. V4 ($94.99) is the value play, and the Dogwood Armory 3-Position FRT is the one you can most reliably find in stock, streeting around $100 to $110 against a $200 MSRP. If you would rather follow a documented, step-by-step install, the NSPEC Mongoose ($84.99) ships with the most thorough polish-and-grease instructions in the category. The Duality Arms Mamba ($150) is the simple two-position choice that keeps your factory selector cam untouched, and the EP Armory BRRRT (about $30) is the cheapest way in if you do not mind the most hands-on install.

A standard AR-15 forced reset trigger cannot work in a KRISS Vector because the Vector does not have an AR fire control group. The Super V system is a delayed-blowback action that drives the bolt and carrier down and back on an angled track rather than straight to the rear, and the fire-control geometry it operates has nothing in common with an AR receiver. That is why every trigger on this page is platform-specific: they are engineered around the Vector's own cycling, not adapted from an AR part.

All six work on the same principle. During the firing cycle the bolt interacts with the trigger to push it forward into reset, which shortens the distance your finger has to travel and speeds up follow-up shots. The shooter still fires every round with a deliberate press: one pull, one shot. The devices assist the reset rather than fire the gun for you, which is what keeps them semi-automatic. If you are comparing this to the reset-assist landscape on other pistol-caliber and 9mm platforms, our AR9 forced reset build guide covers blowback tuning fundamentals, and the FN PS90 FRT guide is the closest sibling, another non-AR PCC that takes a dedicated reset-assist trigger rather than an AR drop-in.

A Vector reset-assist trigger install is friction-sensitive, so the polish-and-grease step is not optional busywork; it is what makes the trigger reset reliably. The Super V action is drag-sensitive by nature, and every one of these devices adds a contact surface inside the fire control group that has to overcome friction on each cycle. Get the contact points smooth and properly lubricated and the reset is consistent. Skip it and the trigger short-strokes or resets unevenly, which is the single most common complaint on these parts.

NSPEC ships the most thorough documentation for the Mongoose: polish the bolt lugs, the Mongoose part itself, and the action rail guides, run high-temp grease or ATF-4 on the contact surfaces, and expect roughly 350 rounds of break-in with heavy lubrication before it settles in. The EP Armory BRRRT roller kit lists about 150 rounds of break-in plus bolt-lug polishing and lubrication, and because its roller is a wear item, plan on replacing it eventually. Gen1 owners have the most work: the BRRRT install on a Gen1 means pulling the top rail and setting travel to about 1/16 inch, and the RATL-R, Continental Customs C.A.R.T., Mongoose, and Dogwood FRT all need an upgraded Gen2 fire control group before they will run in a Gen1 gun. Duality also recommends 9mm RATL-R owners step the mainspring up from the 9mm to the 10mm spring so the trigger resets consistently under the added drag. Any device you add to the fire control group voids the KRISS factory warranty, so go in knowing that.
