IIRC the MVP uses any trigger that works in Howa 1500, Weatherby Vanguard and the model of Smith & Wesson bolt action that took the short length mounting tang trigger assembly.
TK,
Jard and a couple other outfits make triggers that fit the MVP. They might not be listed as such but the MVP uses the same aftermarket triggers that fit the ATR, 4x4 and late Howa 1500.
