I saw those years back when Jason and Abby owned QD...Jason just never got around to producing them, the CNC machines were too busy making AR stuff. Other than it should have a hole in the back so you can push a cleaning rod from chamber to muzzle (big oversight), it looks like a nice design. I haven't been in the shop since Jason & Abby sold it, but generally the QD stuff is nice. $99 is a good price for the feature set.
