After playing with this thing a bit, I'll offer my observations. First, I believe the extent of the owner's satisfaction is going to depend a lot on expectations, and experience with other triggers. My guess, many of the folks who offer rave reviews on this trigger may have limited experience with true, match grade triggers. This is an improvement over the standard Royale trigger, but only if you need a lighter release weight. As Ernest mentions in his adjustment video, the various set screws are fine tuning devices only, the release weight is not adjustable, you have to experiment with different springs. The standard spring gave me a let off of around 9 ounces, with a light, but usable first stage. Using the standard Royale first stage spring (the one easily removed from the trigger bar), gave a release of between 4 and 5 ounces, with a relatively useless first stage. But although useless in shooting technique, still necessary if you want to maintain a safety margin in moving around with the rifle. I found some spring stock in my old Brownell's supplies that gives a let off weight between the two, around 6 ounces, and is the one I will use.
So, IMO (worth what you are paying), the standard Royale trigger is fine for general purpose field and plinking use, and the one I prefer if I'm going to be knocking around with the rifle in the woods.I loathe the spring-and-ball adjustment screw, but it works in a reliable manner and gives a good release. Mine adjusts down to around 9-10 ounces, which is fine for field use.And its simplicity makes it very reliable. If you want a light pull trigger, the Boss match trigger offers that capability, but like most quasi two-stage triggers, the first stage will not offer much usefulness. But, in fact, that is the case with real two stage triggers too when you get down in light pull territory, and I prefer single stage triggers for that use. I'll now mention what I consider the real potential problem with this trigger. Its reliable operation depends on the fine settings of a couple of small grub screws, not a design to which I prefer to trust my trigger operation. Once set where you want them, I think a small amount of light strength thread locking compound should probably be dropped on them for reliability. Although neither location is subject to violent movement, there is a small sharp movement with each cocking of the rifle, and I don't know how long the little screws will maintain their settings. So, it is an acceptable trigger for target shooting, but if you are expecting something to rival the action of a RAW or Steyr match trigger, this isn't it.
One final note, the safety design is not what is shown in Ernest's video, which shows a flat head screw attached to the safety. If you try that setup, you will be frustrated to learn that even a flat head screw will not reach the trigger roll base to block it from firing, There is now a long grub screw included in the package, and that attaches to the rear of the trigger base and passes through a hole in the trigger rail (lever) to reach the grub screw in the standard Royale safety. Probably a better design, would have been helpful if they had instructions.
