I have the .17 HMR Acu bolt. It is accurate. The trigger pull is okay, but the trigger itself is narrower than I am use to. Mine came with a 4x scope which I swapped out for a 3-9x scope from my 10/22. The 4x scope works fine for the 10/22 shooting at 50 yds. The only other issue I had with the gun, and this may be germaine to the .17, was an occasional stuck case in the chamber. I take a wooden dowel with me to ram out the case when I shoot it. This problem seems to be going away as I break the gun in.
