I sadly ruined my beloved Knight Disc Extreme last season. The barrel is badly pitted and accuracy has gone to heck. It was MY fault, not the rifles. I got caught in an all day drizzle without a muzzle 'rubber' and the BP (yes I mean real black powder) ate the barrel. I was not able to clean it after firing for several hours and that was all it took. So.... what to buy as a replacement? I have not had luck with T/C. My Omega was not accurate or consistant. With Knight's future uncertain (yes I know they have been bought but who knows when production will resume) what should I buy? I want the rock solid strength of the Disc design, the accuracy of the GM barrel, and the absolute lack of blowback that I had with the rifle.
