Epic look that's design could be better - Tyrant CNC NexGen AR Collapsible Buttstocks

This is an epic design and looks great. However, there are a couple of things that would prevent me from ordering this again. 1) The carbon fiber top piece fell off as soon as I took it out of the box. I literally turned it upside down to look at it and it fell right off. 2) I store my firearms with the buttstock collapsed. When I get to the range and get ready to shoot, I always forget to extend and it's a quick squeeze and pull and I am ready to go. This is not as friendly as your standard stock. It does not have a means to stop it from sliding off if you pull too far. If this design had the paddle design to it, it would be quite easy to extend. For these reasons, I can only give it a 3/5.
