I have a MkII JTV (jacaranda laminate thumbhole stock, varmint barrel). I've been more or less happy with it, but the stock doesn't fit me well for prone shooting. Can't get a good cheek weld and the LOP is too short. Were I to do it over, I'd get a MkII FV and add buttstock spacers and an adjustable cheek piece. Alternately, I'd opt for a CZ453v.
The accutrigger has been great. I've still got it at the factory setting, but am thinking about lightening it a bit.
The machining is a bit crude, but the action is smooth. I have some issues with failure to eject empty brass. Instead of throwing the brass clear, sometimes the cartridge bounces around the receiver and gets stuck between the receiver wall and the next round.
The rifle shoots subsonics and target ammo well, but HV and hypervelocity are just about useless beyond 50 meters. When I'm shooting well, prone with a bipod in the back yard, I'm getting 15mm 5rd groups at 50 meters. If I were more comfortable with the stock, I'd probably do better (the rifle shoots better than I do, presently).
