What kind of options are there for an out of the box full auto capable .22LR upper.

I know there is the Ciener M16 conversion, but from what I have read you should use it with a dedicated upper.

I asked Bushmaster about theirs and they say it is semi only. I am looking for a one I can just  put on my lower and  go to it.  

any info is appreciated.

Looks like someone posted basically the same question earlier today

Your answer is within the link you provided.  The Kuehl and Accuracy Speaks barre;s are made to use the Ciener slide and bolt, as the face of the barrel is cut like the Ciener chamber adapter' face.

Look closely at the chamber end, see how it look like the Ciener adapter ---

I am presently building a a large hole upper for my colt using a Kuehl barrel. But it going be semi-auto though......
Anyway here is a link to a site that uses the Kuehl barrel and a modified Ciener m16 unit. It has some cool videos!!

Good Luck

BTW, I was able to get the 30 round mags for Kuehl for $59 with the kit
