Well I installed my Timney in place of my Accutrigger on my Model 12 .204. Install was easy but Timney's instructions are a bit outdated. I followed Jard's instructions and ignored the part about the sear. My experience with the setup is it breaks nicely as the sear is easy to set. Adjusting the Safety/Overtravel screw was much easier once I found Jard's instructions and realized its purpose. The main issue with the trigger is the set screw that it comes with for the weight adjustment is too long. In order to get the weight down to "target" quality it needs to be backed out to the point that it bottoms out on the stock thus tripping the trigger when closing the bolt. The trigger works well and it does reduce pull weight but in order to really get it down I would suggest a shorter set screw that allows you to screw it in further without creating excess tension.

The trigger does what is says. I doubt I could get down the the advertised 1.5 lbs and am more like 2-2.5 right now due to the screw interference issue. The break is clean however and it feels pretty good. If the Jard or SSS is an improvement over it in terms of weight I would suggest either of those options instead. If you don't mind fiddling a bit the Timney might be improved upon. They do need to update the instructions however as they are bit confusing as written for the Accutrigger model.
