So, I was looking at the uppers on your site, what is the difference between the ".22 Evolution Sierra Dedicated Upper " and the other uppers? It looked like they all had the same  features otherwise.

Sierra has a low profile gas block. It can still be up graded with all options.

OK,  so they have the same upper and "evolution" bolts, but different barrel contours, hand guards, fsb/gas blocks.
Think I'm starting to understand, unfortunately I think my wife is too.
Thanks

Correct. Seperate checking accounts are a good thing.
