Think long and hard. - Tasco 10-40x50 Target / Varmint Rifle Scope

For a cheap scope, it may be ok. Out of the box brand new, couldn't get the scope to zero without shimming- ran out of up elevation. Considered purchasing a base with 10 or 15 degree MOA, but called Tasco instead, and informed them of the issues of running out of elevation adjustment. They told me to return it to them- which is actually Bushnell. Initially, they wanted me to pay ALL shipping costs- to them and back. Took a little time, but they got the point that they were going to honor their "Limited Lifetime Warranty" for a faulty brand new scope WITHOUT any additional cost to me. The faulty scope got past QC which may be rather common, just like BSA. Tasco sent a replacement instead of a repaired scope which I actually received from UPS today (08-13-2012)and hope to try it again at the range Sunday.
The scope focus is not as sharp above 30X. Still, beyond expecting a scope that works out of the box and having to get Tasco to make good on the warranty, you generally get what you pay for, and can expect Burris, Mueller or Simmons quality for Tasco money.
Pros: Inexpensive, full of features, better than iron sights.
Cons: VERY POOR quality control.
