Wait a second, you want to blow $1500 to get a rifle capable of 1/4 MOA, but your putting on a $400 dollar scope?
I'm not knocking the Falcon scopes, I have a 2.5-10x myself. Just think your priorities are a little misaligned.
Your rifle is probably very capable of producing 1/2 inch groups at 100m. Nothing wrong with that at all. If I were going to spend any kind of money to tighten things up a bit, it would be on a bedding job, and getting the trigger adjusted to where you want it. If I had $1500 to blow than I'd probably start to look at some of the better quality scopes.
Buy lots of ammo and get to the range often. That will improve your groups more than anything.
