Dorin XPRT90 Forced-Reset Trigger

The Dorin XPRT90 forced-reset trigger is the premium PS90 trigger upgrade. Forced-reset trigger systems use a mechanical reset path that cycles the trigger forward after each shot, which delivers a much faster splits than the standard semi-auto trigger pull. The XPRT90 implements this design specifically for the PS90 fire control group, with nitrided 17-4 stainless steel hammer and sear plus a 3-position aluminum selector that replaces the factory selector.

This is not a full-auto conversion and ATF currently classifies forced-reset triggers as semi-automatic, but state laws differ. California, New York, New Jersey, Washington, and several other states ban or restrict forced-reset triggers; verify state-specific legality before ordering. The XPRT90 is also NOT compatible with full-auto registered PS90 trigger packs.

Dorin lists ship dates of August / September 2026, so this is a pre-order product through FN Specialties. At $450 it occupies the premium tier of PS90 trigger upgrades, intended for shooters who want the fastest split times the platform can produce while remaining within Title I regulations.
