Be prepared to do some fitting...
Originally, I thought that maybe it's because I have an aftermarket bolt, but I could not lock the bolt back. I was only able to lock it back once after 10 tries or so, and none after. I reinstalled the factory part, and the bolt locked back every single time. I then reinstalled the VQ part and it still failed to lock the bolt back. Comparing the 2 parts side by side, the VQ part that I received was about 1/16" longer than the Ruger part, but had the same 45 degree angle. After filing the VQ down to match the same length as the Ruger and being careful to match the angle, the bolt now locks back every single time. And, yes, the auto release function works. Well worth the time and effort of figuring out the issue and doing a little 'smithing to make it work.
