My CTR's wear Nightforce. This is the longrange forum, but I have to ask how far do you intend to shoot? Everyone's eyes and preferences are different, so you are going to get a schidt load of answers. A CTR is not a lightweight hunting rifle, so why limit yourself to a 6x scope? If shooting real small targets out real far, I'd go with something with magnification. Fill us in on what you are wanting to use this rifle for. The scopes I use, are great for the shoots I do, which are small targets out to 600+ yards. An example is a rabbit silhouette at 611 yards, a yote at 800 yards.. For my eyes, the 5-20x56 SHV are a minimum.. Those are sweet rifles, you will be happy with how it shoots. My buddy has an older T3 stainless varmint model with a 24" barrel and it is scary accurate. The CTR is pretty much the same way, but with a better bottom metal and magazine.
