WHat all did it take to fix it?
It took several set screws to get the ejector on the mag to line up perfectly with the bolt. First I adjusted the top 4 feed height/angle screws and put 2 set screws on each side of the magazine to keep things centered. I also made a tall mag follower so that I could have a hold open tough enough to stop that heavy and fast moving bolt. That cuts way down on dry firing because these things run through firing pins. Also, a pistol should stay open on empty. This along with a Volquartsen Xact Edge extractor and extractor spring for a Ruger 10/22 rifle got my failures down to 1 every 50-75 rounds which is still unacceptable. A set screw at the top of the mag well on each side wound up locking the mag in place where it needed to be. My next trip to the range netted 560 rounds failure free.
This doesn't sound like much but it took forever staring at it and trying to figure out just what to do to make it work. In the end it was worth it.
Noneya - I made that mount out of some 2in non mil grade aluminum angle stock. I used the front axis as one mount point and drilled and tapped the upper reciever and the non functional half of the recoil spring guide rod support block for the rear anchor. Risky to say the least, but it was to cheap to not cut into it. If I hadn't decided to bastardize it then it wouldn't be running right anyway. I also bobbed the right side charge handle protrusion and rolled the left side out for one finger opperation. I like it better this way anyway. The rail screwed to the top of the mount is a Weaver rail that was on an old pump shotgun that I bought some years ago. Not top notch work but damn it was cheap! I'll probably smooth it and paint it black at some point. For now... it works.
Dust - No recall that I know of. They do not have what you would call a glowing reputation for proper function.
