I like my triggers to be light and clean enough to shoot off hand with. Not all rifles are the same. My AR's are different from my bolt guns, and they are all different from each other in design so I often make do. I have taken a dislike to CZ's set trigger units over the last few rifles. Some were just plain defective. I have taken a "skip to the end" attitude and started ordering a new Timney with every new CZ 527. I haven't been disappointed until the one I installed on my 527 Varmint in 6.5 Grendel. No matter how I adjusted it there was a noticeable/annoying amount of creep before breaking. For a varmint shooting from a fixed position it would be fine, but for off hand shooting I found it distracting enough to order a replacement. I installed it this morning and was very pleased with the results. After adjustment, about two pounds and crisp. I can live with that. CZ has taken to sealing over the sear engagement screw. I wouldn't mind that if they didn't send it off with the screw backed out as far as possible. Out of the box and on the gun the trigger pull was like five miles of bad road. I dug the sealant out (easy) and adjusted the sear engagement before attending the other settings. If you're going to try this, it's like a 3/32" Allen wrench. ~Muir
