I'll pass on the squirt-gun barrel until I can acquire another suitable receiver upon which to mount it.
Regarding the attachable rear-sight tower mount. Does the mounting of it on the flat-top's rail not offer less structural strength and more probability of dislodging the sight mount and settings? I'm all for increasing adaptability and interoperability, but not at the expense of decreasing reliability. Is there a potential credibility issue with the concept of a basic gun and having all sorts of mission-tailoring widgets hung on it? Sort of a sub-optimization problem?
