I have one on my 300WM Sendero. My understanding is they are not made/sold anymore.
I do like the trigger and the option to have a nice hunting trigger or a precision target trigger. The only trade off is the 6oz trigger is a bit mushy, and has a long jump back which can throw one off. This would probably not be such an issue if I had a vertical type stock on this rifle like a McMillan A3 Sporter as my other rifles do. This particular gun is the factory stock so the reach to the trigger when in set position is a bit long.
With more funds available than when I installed this trigger, I'd just go with a Jewell set at 1-1.3 lbs. I have one in my 338 Edge and it shoots every bit as good without the funny jump back tradeoff. When I update this particular rifle, I'll probably go to a Jewell.
In general, I do like the single set trigger concept. I also have one in my CZ 453 22LR. Amazing.
