Knight has made some running design changes so far as the muzzleloader breech plug, the hammer travel and hammer spring strength, and may make further changes as the model is refined. I would not hesitate to recommend one at this point, especially in the centerfire or rimfire configurations. Knight has definitely proven to me they have perhaps THE best customer service in the industry.
The rifle is balanced well, handles recoil very well, and is not at all hard to look at. Mine is now wearingtwo of the changes that should now be incorporated in production. My shooting has been halted by heat and insects but I will try to add more up to date infoto my tedious report at
