I know the mk2 are suppose to have the accu trigger, but walmart's version does not. It's an older model. And I've read on several other threads that the trigger on the mark f without the accu trigger is horrible. Some saying it was 8-10 lbs and grainy. Definitely set on the marlin, especially since its made in the USA that's really how I decided, now I'm just trying to find the best deal for the xt-22.
