@Djfan ,
I have multiple lower priced scopes on my rifles.
Like anything else, if you take care of it, it will last a long time. (I honestly don't know what people do that they keep having to send scopes back in for warranty repair! I have never had a scope "failure"!)
The Vortex Crossfire II is a decent scope for the money! I have 2 of these.
Equal to the Diamondback series at half the cost.
Only issue I have with the Vortex scopes is they tend to flare out easier than other scopes.
Sightron, you get a lot for what you pay. I have 3 of these.
An SI, a STAC, and a SIII.
Really decent, bright glass. Hold well, and not bad in lower light levels.
Burris Full field, I have 3 of these.
For $200 or slightly less they are really hard to beat.
Only issues I have with them is that there will be one knob that is stiffer than the others.
At low light levels, it's really hard to find the reticle.
Crimson Trace, I have 3 now.
The Brushline & Brushline Pro both have a BDC reticle available.
With the Japanese glass, now you are getting into really good optics!!
All the controls operate smoothly.
The least prone to flaring out vs the other scopes mentioned.
Really decent low light capabilities.
If your looking for an MOA reticle, their 3-9 Hardline can be had for right around $200.
