I have a Harris on mine (in .22WMR):

...with a Leupold VX-II 4-12x 40mm adjustable objective scope.
The rifle also has the VQ target hammer and extractor upgrades. I've probably fired well over 1000 rounds through it since getting it this past winter and have yet to experience a single FTF/FTE problem. Groups are consistently under 0.25" (10X) at 25 metres using CCI MaxiMag ammunition.
I'm more than happy with the rifle.
