Just to clarify my thread, my issue was the rail getting canted following basic installation instructions. However, once aligned and tightened it's GTG.
On the subject of rotation, here's caporider's post on another thread I started on modifying the Omega.
--"I'm guessing most folks buy the Omega because it is just about the easiest-to-install freefloating rail out there, and we know DD makes a quality product. The top rail being "continuous" is incidental. For me, the fact that I can deflect the rail using hand pressure (it does return to the correct position once pressure is removed, of course) makes it a no-go for bridging across from the upper receiver. There is also no rotational limiter on the rail - it relies on friction against the barrel nut, which in turn relies on being torqued to spec. FWIW, my factory Noveske MPL barrel was torqued to about 15 ft-lb and was missing the gas tube roll pin, so a potential chain of failure modes with the DD rail does exist. The Omega is great for mounting all sorts of stuff, but I personally would not mount up a magnified optic, nor would I bridge over from the upper receiver (I guess I said that already...)."

To be fair to DD, I havent seen or heard of anyone else havgin the same issue with rotation.
