I have had 2 buds return these rifles.
A guy Ive hunted with for year bought a Wolverine a few years ago. The spinning safety would not stay in one place. He had the rifle for 2 years and twice tried to pull the trigger after stalking and the mechanism had spun into the safe position so he missed the deer. He sold the rifle for 50 bucks and told the next guy to lock the extra safety open.

My bud bought his dad once for this Xmas and it has the disc feature. He had the disc blow out of the rifle 3 of his 1st 5 shots with only 2 PyrodexPellets 50 grns each. He called Knight and they said it was a prob with a spring or something and that it should correct itself and if it didnt he could purchase a new spring for his rifle. He explained that it was brand new and it still didnt matter. He said their cust service was awful and he decided that instead of a new spring installing a new Thompson Center Omega was the way to go and said he would never recommend or buy anything Knight puts out again.
