I have that rifle. Don't put it down for it's price. I shoot echo silhouettes out to a 1000 yards with mine.
For $200 just put a Nikon Buckmaster II (if you can find one) or a Vortex Crossfire on it. Probably the best scopes for that price. I also picked up a Sightmark off of Sportsmansguide 5 years ago for $100 I thought for sure would crap out by now in the extreme temperatures, but it is still working just fine on my son's 6.5.
