Dave: I think Dan above is correct, in that a BSA scope will disappoint when mounted aboard a 204R. If funds are the issue (usually is for everybody), I'd suggest saving a bit longer and treating your eyes to a better optic, and also be able to better take advantage of what the 204R offers. It's hard to hit small things at 400 yards if you can't see them clearly.
I'd also suggest more magnification, although you don't say what you'll use the rifle for, just the range you intend to shoot. I'd suggest something like a 6.5-20X also. I've found that the 40mm objectives allow plenty of light for 99% of most shooting, and also allows lower scope mounting over the bore, which most experienced riflemen prefer (it also minimizes rifle/scope canting).
Below is one of my Cooper M21's outfitted with a Leupold 6.5-20X 40mm LR M1 scope in Leupold Low Rings (30mm).
Look at Nikon or Vortex as Leupold alternatives. I'd rather have an unscoped rifle in the safe while I saved, than run out and buy cheap Chinese glass just to get to shoot the rifle. Remember, in optics, you
REALLY get what you pay for.
