What's your budget?
What distance are you planning to shoot?
What focal plane do you ant the reticle in? FFP or SFP. There are pro's and con's for each of them,depending on the main uses of the gun.
I wouldn't waste any money on a scope that's not going to do everything that you need it to. Buy once - Cry once! Even if you have to save more money to get a quality optic,it will be worth the wait.
You can also find some great deals on used scopes,and get a better quality scope than you'd get if buying a brand new scope for the same amount of money. Most scopes today have Lifetime warranties,so most used scopes will be covered.
Scopes that I'd look at -
Sightron SIII
Vortex Viper PST
Athlon Midas BTR or Ares BTR
Burris XTR II
