Real nice choice! The only two things that would stop me from buying this fine rifle are...
1) I prefer the break-actions over bolt-actions because less moving parts means less wear & tear plus the break-actions like the Knight Revolution and the T/C Omega are easier to clean.
2) The Disc Elite does not come with open sights. I prefer open sights on all my rifles. All mine that are scoped have open sights & see-thru rings.

Here's a nice review on the Knight Disc Elite
