I just put a Vortex Crossfire11 on my PCC I don't have. For a $199 it is a heck of a sight. I have the Sparc11 on a CX4 Storm and it is $100 more and is no better of an optic in my opinion. The newer red dots seem to be much smaller. Worth a look.

This ^^^^ I have both as well and I will purchase the crossfire anyday over the Sparc in the future. The skeletonized mount is a big bonus as well depending on what your mounting it to, as you can still use iron sights that are of the lower profile style, like a shotgun.
