The Honey Badger is super cool, in my humble opinion. The cheek weld on the PDW stock kinda sucks though.... where the receiver extension ends is right at your cheek bone, so you either have to crane your neck froward to get on the receiver extension part, OR sit up right and use an arm from the stock. I have a soft spot for PDW stocks, but more as a CQB thing. The LWRC UCIW is about the same length collapsed, and provides a better cheek weld. Not nearly as sexy though!
The Sugar Weasel is cool, but it's just another AR. If you're going to spend Q money, and are married to getting a Q, get the Honey Badger. If you just want a cool blackout as a thermal host, there's other options that may be better suited.
Edit: The Sugar Weasel is not as expensive as I thought.... upon further inspection, looks like it's about the same as a DD, which was what I had in mind. Solid value!
