well here's the deal I just purchased a knight bighorn. and the front sight is too tall. it shoots about 4 inches too low at 50 yards with the rear sight all the way up. anyone know where I can purchase a shorter front sight. I called Knight rifles and they're sending me new shorter front sights. but I don't know how long this will take. and I want to go shight in this weekend or sooner. I just need something to get me by. anyone else have this problem with the Bighorn. if so where do you get your replacement sights and yes I have tried several different powder charges and several different grain bullets. and the local muzzleloader shop owner is in Alaska. on a hunting trip.
