Two pins in the mechanicism broke to the point that the gun wouldn't fire. The Knight had this same problem in the NRA magazine's review with the walnut stock but Knight presumably corrected this with the synthetic stock. Anyhow, we had a local gunsmith temporarily repair the trigger in order to use the rifle for the arriving whitetail season. We contacted Knight, told them about the broken trigger, they are shipping a complete new assembly. After logging to this webpage and reading the above paragraph, Scott left me an e-mail.
Web page looks great.
I have only one suggestion. He's right, the Knight Disk rifle is throwing tight groups with 289 grain sabots and 3 Pyrodex pellets. Don't forget that the muzzle energy produced by most muzzle loading rifles will drop from half to a third at 100 yards. In other words, a rifle that has 1000 ft. lbs. of energy at the muzzle will only have 300 to 500 ft. lbs. at 100 yards. My son likes the heavier loads for this reason.
