This stock is solid with no wobble. Plus, it looks cool and the orange anodization on the inner tube is a nice touch.
The collapsing feature works easily yet stays in place. It fits perfectly on a stock Stryfe. It will fold down partially on a Stryfe with an extended battery door, but that may put extra strain on both the tray, stock, and the attachment point itself.
Even if you never collapse this, it's a nice, low profile stock that's plenty solid.
To nitpick, and this may be mine in particular, the holes drilled for the adjustment nub are slightly off center. It's barely noticeable and I'll happily buy another one. You should too!
