I am looking at getting one of the newer Knight Revolutions II in .50 caliber. It has a more refined trigger and different lever for loading. Does anyone have any experience with the Revolution II, not the first one. I heardthe first onehad bugs in it and that was confirmed bya techwho told me it did on the phone today. Something about blow back and bad trigger. This supposedly wasdealt with in the newer model.Any info will help.
