So far, mine has improved my shooting. I used a supermatch 455; it was a great shooting rifle on it's own, but since it went thi the chassis, groups have definitely tightened up a bit, and are more consistent in size and shape. The only thing that I found undesirable was the MDT Pistol Grip; it just felt cumbersome in my hand. I have since changed it out for a cheap, black AR grip which fits me much better.I made a few upgrades to my CZ457 MTR
now with IBI barrel and MDT Oryx Chassis. I am still trying to figure out if these upgrades improved the accuracy:

My ex-gf had an At-One 457 and it was very nice. Some people don't like that stock but its nice.My recent cz 457 at-one I’m not usually into wood stocks but this one tickled my inner termite. I bought the rifle set up like this without optic. I decided on the arken scope after countless YouTube videos told me so. I’m pretty happy with the arken overall. The one thing I didn’t like was the LOP of the at-one. Extending the awful butt pad out far enough, made it wobble all over, and look like a spoiler on those cars I hate. I attempted to resolve the LOP issue by stacking up some rubber strips and aluminum like a licorice all-sorts. The adjustable height pretty much added itself.
