I recently put a timney replacement trigger in MKII in .257 roberts, not too hard but there was some filing and inletting that needed to be done for proper fitting. A gunsmith would probably be a better option but I did learn about how a trigger works. BTW I can not believe the difference between the factory and replacement trigger, night and day. I did find instructions on tuning the factory trigger on some forums but it should only be performed by a qualified gunsmith, it sounded like itinvolved changing the angle of engagement between the sear and trigger.

I also have an H-S precision stock on order for this gun, should be getting it soon. From my research it sounds like MacMillian is themost recommendedfor anaftermarket stock but they are not cheap. Good luck.
