Not AAC. I bought a Rugged Surge, and I really like it, but its heavy. I like the modularity of being able to run it as a 9 inch or a 7.5 inch. They do have a "throw it off a cliff warranty, however, I've never had to use it.
My next can will be a Thunderbeast direct thread.. Their cans are raved about by everyone that has one, or so it seems. They also sponsor a lot of matches and give a lot back to the gun community, which is pretty decent.
