Workable buffer tube but meh - Kaw Valley Precision Mil-Spec 6-Position Buffer Tube

This carbine mil-spec buffer tube is not centric and was clearly elliptical when trying on several lower receivers. It does still fit, and stock and buffer components do seam to work well enough. The groove for the end plate is cut a little too deep and allows some end plate tabs to "skip out" when tightening. Overall it will work if you get the right combo of components, but I've had seemingly better machine buffer tubes for less.
