Having had the same rifle, the Knight Disc with the orange primer jackets, I converted it to the Lehigh Conversion to shoot bare 209 primers. It was a real accurate rifle and with the conversion a pleasure to shoot. I sold it.

I then purchased an Optima Magnum (not the V2 model. Different barrel release location) and purchased it new for $209.00 and it currently has a Redfield Scope on it. Just a real nice accurate rifle to shoot and easy to clean.

Of the two, I like the Optima better. It suits my needs.
