My origin is a sa standard bolt face, fitted with a TT diamond, in a krg bravo, 25 creedmoor. It's decent, has some noticeable cock on close and more firing pin fall than needed, plan to get it tuned up. I do not own a tenacity, but my friend does, it's a BadRock chassis rifle in 6.5 prc so it's the intermediate length. It's pretty nice, very smooth, I personally haven't shot it, just played with it a bit. Another action in this ballpark is a kelbly atlas tactical, they run 900-950$ and are very nice, have an adjustable trigger hanger and mechanical blade style ejector, comes full nitride and is very smooth and tight, no slop in it at all. The only superior feature of the other two compared to the kelbly, the origin has swappable bolt heads and it has somewhat of a control round feed feature, but it's not 100% reliable in crf function. Prefit barrels are available from several vendors for the kelbly and origin, but have saw none for tenacity. That's my input!
