Has anyone owned or had any experience with a CVA Optima Elite rifle, With the interchangeable barrels? I have owned a few TCA Encore rifles, But I have never shot one of these CVA rifles. I am considering buying a used one with the stainless 30-06 barrel and a stainless, fluted 50 caliber muzzleloading barrel. It seems like a VERY reasonable price, just would like some opinions from somebody that has owned one, if possible. Thank You for any advice that you can give me.
