My advice is save a little more money up and buy a good scope instead of these cheaper ,lower end scopes.They'll cost you more in the long run.I can't see buying a decent rifle then top it off with a cheap scope. The rifle can only shoot as well as the scope,ammunition and shooter will allow.Check several shooters supply houses and you can find good deals on good scopes.
www.Midsouthshooterssupply.com has a Leupold close out going on right now.Do a little researching and you'll find good buys on good scopes.Like has been said millions of times before "You get what you pay for". This is very true in optics
