They are tough. My uncle dropped a rifle on a concrete floor while cleaning it after a hunt a couple of years ago. This was a heavy, wood stocked Sako, and it landed on top of the scope, a Burris Fullfield II 3x9. It made a sickening noise and thought for sure the scope would be ruined. Upon inspection, the top turret on the scope was crushed inwards, but that was the only visible damage. I was really surprised when I shot it. It worked fine. I wrote to Burris and they sent me a new turret cap for free, albeit 9 months later. That scope is still in use and works well. I'd be willing to bet some of the more expensive scopes on the market would have broken.
The Burris ballistic plex reticle is fairly simple, clean and easy to use compared to most ballistic reticles. That said, I recommend you shoot your gun in at different ranges rather than just relying on the info they provide with the scope. That way you know for sure what those hash marks represent distance-wise for your gun and load. The glass is ok, not as good as the Bushnell 4200's, but for they money they're good values.
