Reading a little on AR based platform wildcats. Anyone have a 6 WOA based AR ? What are your thoughts and performance based off your usage.

I have two. One is a "Spacegun" that I used for XC competition. It's a real hammer. I've shot more 200's rapid fire with it than any other gun. My 600 yard scores have been in the 195 range. I like it. My other gun is a 10 twist varmint upper. I like it not so much.
