I did contact them first, they haven't tried the timney tikka trigger in the chassis yet. They did say that all other timney triggers that they tried worked without any mods so I think it would probably be ok but I'd like to know for sure before buying. I'm sure someone must of tried it by now.I would reach out the guys from KRG. They are a nice guys wealth of knowledge on Tikka/Sako rifles. I believe the Sako TRG trigger will fit, but don't hold me to it. I think that KRG was actually developing a trigger system.
That one would be perfect. Thanks.KRG just came out with a trigger for the Tikka. It is on the front page of their web site. There is a discount for early adopters.
