I have a stainless version. Everyone who's shot with it loves it. With rim fire you get more than a few FTFire, but who cares when the brick cost the same or less than a 20 rd box of 5.56.
The .22 rd is surprisingly accurate despite the twist rate.
Chris, the front of the .22 adapter is shaped like a .223 case and sits in the chamber. The .22 round has its own chamber behind that. There is a slide within the adapter that gets blown back againsts a smaller spring. The slide holds the extractor and is charged with the standard charging handle. The AR buffer and spring sits idle the whole time.
If one were inclined to build a .22 pistol with an AR, the buffer tube, buffer, spring and stock can be ditched. A cap can be screwed into the rear of the receiver.
