Got the parts yesterday from Knight and all fit perfectly. The disc rifle now shoots 209 primers without the need for the plastic holder. The tolerances are too tight for Remington primers but CCI's fit ok. The plan is to hit the range tomorrow to sight in three in-lines. The Fire Hawk now has a new scope on it, 3X9X40 Tasco world class. The Knight is wearing an older Redfield 2X7X32, the TC Triumph has a Leupold 3X9X40 Rifleman series. Son wants to shoot 777 powder in the Firehawk, me I'll set the Triumph and Knight up with Black Horn powder.
