If you decide on this particular sight... make sure you buy the 3rd axis scope rod holder. The scope rod holder will protect the overall life of your scope and is, I believe, essential when using this sight.
Limitations? None as far as I know of. I use the exact sight with zero problems.
If you can find one anywhere close to $100.00... buy it. Normal retail for this sight is in 175.00 ballpark [without scope].
Additionally, I found the Extreme brand to be a good combo with the Challenger... but [like anything] that is a matter of preference.
Good luck.
