I've seen a few of the Rem 504s uses for hunter class in silhouette now. As you said, making them competitive at the upper end of competition is a project. Overall, they are about as accurate as a CZ452 but with a much better trigger. Not to say that the Rem trigger is anywhere close to the top-end Anschutz triggers, but it's a lot better than the CZ triggers. The barrels are about on par with the CZ barrels and are plenty accurate to shoot well for targets as large as we use in silhouette if you break all your shots in the middle. Be prepared to be disappointed every once in a while if you break toward the edge of the animal and it doesn't fall. I like the feel of the Rem 504s, and the flush magazine is better than the protruding CZ magazine, even the old BRNO magazines that some use in their CZs so the mag doesn't protrude from the stock quite so much. All in all, it's a little more expensive than a CZ452 and you get a little better trigger and faster lock time with it. Add a Timney trigger to the CZ, though, and it's a neck-and-neck race. Both guns are good. Either gun needs a custom barrel and extensive trigger work or new triggers to be great, though, and bedding usually helps both also. A couple buddies got the Rem 504s when they first came out, and they paid through the nose for them then. I was hoping to have something to compete with the Finnfire as a step between the CZs and the Anschutz 1712, but after shooting the Rem 504s I decided to just stick with the CZ and keep saving for the 1712.
