Duality Arms PS90 RATL-R

The Duality Arms PS90 RATL-R is a drop-in trigger system for the FN PS90 that the maker positions as a reset-assist upgrade, taking its name from the KRISS Vector RATL-R lineage. The primary assembly is CNC-machined from 7075 aluminum and paired with a lightweight three-position selector made from carbon-fiber-reinforced polymer. Install is drop-in, with no modification required to the factory fire control group.

Duality Arms describes the RATL-R as a performance-focused system for enhanced control and faster, more refined handling rather than explicitly labeling it a forced-reset trigger, so treat its reset behavior as vendor-stated rather than third-party tested. The kit bundles a magazine insert that converts standard 30-round PS90 magazines to 50-round capacity, and the company lists compatibility with the Strike Industries PS90 chassis.

The RATL-R undercuts Dorin's XPRT90 by a wide margin while keeping the same third selector position, and it is the only PS90 reset kit that pairs a machined metal assembly with a no-modification install. As with any reset-assist or forced-reset device, legality is state-specific and changing; Duality Arms will not ship to sixteen jurisdictions. Verify current federal, state, and local law before ordering.
