An old cowboy once said, "good saddles ain't cheap...And cheap saddles ain't good..."
The same can be appied to just about anything in the gun & optics world.
I have been impressed by cheap scopes a few times, one of which is the Vortex Crossfire line of scopes. My buddy bought one as a quick & cheap scope to test out a new to him (used) rifle before deciding on taking it to the gunsmith to build a custom off of, just to see how it would shoot in stock form. He ended up liking the scope so he put it on his hunting rifle. I was pretty impressed for a $150 scope. I also recommend getting the BDC reticle.

I also recomend the DNZ 1-piece Gamereaper mount. Lightweight and strong. They're about $70.
