Found these in store at my local Atwoods. This is my first experience with the Hexmags. The first gen had problems but reviews I looked into say the Series 2 are Good to Go. My only gripe is the base plate is a bit wide; you wouldn't want these for a double stack mag pouch.
I think this a huge barrier for many people. Fortunately, satellite internet will change this very soon. Starlink won't have low enough latency for gaming but will be plenty fast for everything else.
