A few years ago I had the opportunity to fire out to 500 yards. With both the standard model FS2000 and the MSAR STG-556, both with the factory optic, and mixed brass 55 grain blasting grade reloads, shooting off the bench, I had no trouble hitting the man sized silhouette at 500 yards. Both rifles were zeroed at 100 yards, the aim point was the top of the head, and we could hear the pings. I was very impressed (that I could still see that far). I wonder how badly I scratched the paint….
